C/C++ Programming Help Thread

Yeah I seem to remember it's the \r or something.

Instead of saving the end of line as ending \n, it's saved as \r\n, or something like that.

Try it with a different editor, I seem to remember that one of the native Windows applications saves it how we need it.

it is a command to go to the next lin i think you can hex edit it away

I am confused; I'm trying to send a list of artists that I read from a file via TCP to the PSP and save it there as a file again. The problem is, the transferred list isn't complete. Im having length-outputs in the server and the client, but it confuses me even more:

Server Code (read file and send string-length and contents):

Code:

---

                pFile = fopen ( "artists.txt" , "rb" );
                fseek (pFile , 0 , SEEK_END);
                lSize = ftell (pFile);
                rewind (pFile);
                buffer = (char*) malloc (lSize);
                fread (buffer,1,lSize,pFile);
                fclose (pFile);

                printf("Sending artist-list-length (");
                sprintf(answer_l, "%i", strlen(buffer));
                printf("%s)\n", answer_l);
                rc=send(sock,answer_l,strlen(answer_l),0);

                printf("Sending list of artists...\n");
                if (rc=send(sock,buffer,strlen(buffer),0) != strlen(buffer)) {
                        printf("send different lenghts; buffer=%i rc=%i\n", strlen(buffer), rc);
                }

                printf("sizeof(buf)=%i strlen(buf)=%i rc=%i\n", sizeof(buffer), strlen(buffer), rc);

---

Client code (recive length and contents and write to file):

Code:

---

                if((rc = recv(socket, artist_list_length_c, 8,0)) < 0) {
                        printf("Error while recieving the artist-list-length; error-code: %s\n",strerror(errno));
                        return 0;
                }
                if(rc==0) {
                        printf("Client has closed the connection before sending the artist-list-length\n");
                        return 0;
                }

                artist_list_length_c[rc]='\0';
                artist_list_length = atoi(artist_list_length_c);
                artist_list_length++;

                char buf[artist_list_length];


                // Recieve artist-list
                rc = recv(socket,buf,artist_list_length,0);
                if(rc==0)
                {
                        printf("Server has closed the connnection before sending the artist-list\n");
                        return 0;
                }
                if(rc==SOCKET_ERROR)
                {
                        printf("Error: recv, error-code: %s\n",strerror(errno));
                        return 0;
                }
                buf[rc]='\0';

                printf("sizeof(buf)=%i strlen(buf)=%i\n", sizeof(buf), strlen(buf));

                f = fopen("artists.txt", "w+");
                fprintf(f, "%s\n%s", timestamp_server, buf);
                fclose(f);

The Server output is:

Zitat:

---

Sending artist-list-length (5180)
Sending list of artists...
sizeof(buf)=4 strlen(buf)=5180 rc=0

---

The Client output is:

Zitat:

sizeof(buf)=5181 strlen(buf)=1448

I'm really confused

PS: I checked the file on the PSP and visually judging it, it could be ~1448 chars
-= Double Post =-
Is there probalby a maximum length in send or recieve?
-= Double Post =-
Ok, I'll just accept that it doesn't work with such a long string (probably because you can't send a string longer than 1448 chars) so I'll have to split it. Does anyone know how to do this (split a string at X bytes)?
-= Double Post =-
Nevermind, it's easy to split strings.. afer all it's an array so that'll be no problem
-= Double Post =-
Can you somewhere find out what the current MTU is?
-= Double Post =-
The german wikipedia says typical MTU for ethernet is 1500... that could be it!

However I thought the socket would do the MTU/splitting-job?!

СУ&am from psp-programming.com answered this issue. You can send any length of bytes but that doesn't mean that you'll recieve it as one chunk. You have to use a loop and recive until recv returns 0.

I'm trying to port my first C game to PSP. It's a very simple game, only like 2 pages of code. But I need to know the equivelent of fflush(); on the PSP. Does anyone know? Also, how do I make the PSP wait for any button to be pressed, then continue?

This guide explains how to make the psp wait for the button to be pressed. :)

Here's the problem: You're using printf before pspDebugScreenInit(). You have to call this before doing anything with the output screen. Also, you have

Code:

---

    pspDebugScreenInit();
    pspDebugScreen
    sceKernelSleepThread();

---

The second line is an incomplete command, and the third one needs an argument (the number of microseconds to sleep - e.g. 1000000 = 1 second). There might be more, but that's what I saw at a brief glance.

Pretty sure this should work

Code:

---

#include <pspdebug.h>
#include <pspkernel.h>
#include <pspdisplay.h>
#include <pspctrl.h>

#define printf pspDebugScreenPrintf

PSP_MODULE_INFO("Counter", 0, 1, 1);

          cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
          sceKernelRegisterExitCallback(cbid);
          sceKernelSleepThreadCB();
          return 0;
}

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
          int thid = 0;
          thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
          if(thid >= 0) {
                    sceKernelStartThread(thid, 0, 0);
          }
          return thid;
}

int main() {
    SetupCallbacks();
   
    pspDebugScreenInit();
   
    int counter = 0;
    int i = 0;
    SceCtrlData pad;
    printf("Press [X] To Start the Timer");
    while(1) {
      sceCtrlReadBufferPositive(&pad, 1);
      if(pad.Buttons & PSP_CTRL_CROSS) {
        break;
      }
    }
    while(1) {
      sceCtrlReadBufferPositive(&pad, 1);
      if(pad.Buttons & PSP_CTRL_CIRCLE) {
        break;
      }
     
      pspDebugScreenClear();
      printf("Press [O] To Stop the Timer\n");
            printf("Counter: %i", counter);
            counter++;
            for(i=0; i<5; i++) {
              sceDisplayWaitVblankStart();
            }
    }
    pspDebugScreenClear();
    printf("Counter Finished.");
    printf("Final Count: %i", counter);

EDIT: You never defined printf either, I believe that could cause some problems.

The correct version would be

You're getting your functions mixed up.

sceKernelSleepThread() requires no arguments and puts the thread to sleep. sceKernelDelayThread(x) will delay the thread for x amount of microseconds (1000000 microseconds in a second).

I commented out lines and found out the PSP freezes due to strcat(recievedMessage, buf); (recieved message has the size 5181 and the strlen 8101 (can somebody tell me why?), for some reason the PSP doesn't freeze whe cat-ing the string, but when exiting the function (=when trying to free recievedMessage?). Does anyone have an idea how to fix this? How would you merge the parts of the string?

Ahh, good call. Thanks.

Hi,
Is there a way I can serialize and unserialize data in C (like in PHP)? I need to send artists and their albums via TCP to the PSP and I need a good format, maybe somebody has an idea for a good way to do that?

Thank you,
Luke

PS: My father just told me something about 'records', are ther records in C?
-= Double Post =-
Ok, I have two ideas to serialize/unserialize, or short to transfer my data to the PSP:

a) Proprietary format. pro: no data overhead, smaller, faster to read/unserialize |con: proprietary (but, what the hell), not readable by humans
this would look like 5bytes for the num of artists, followed by the length of first artist(name), followed by the first artistname, followed by the number of albums, followed by legth of the first album, etc

b) XML pro: readable, ?? con: overhead, more difficult / slower to read and make datastructures out of it

What would yuo choose?

PS: Id have to malloc a lot with either of the solutions, do you think that would be too slow? Is there a better solution?

Issue 2:
I think I'll be having RAM-issues when recieving like 511 artists and 500 albums, what do you think? How much RAM does the PSP have? Would you write the data to a file and then read from it (was that proper english?)? And: Is there probably a small Database for the PSP out there? That would be killer!

Thank you if you can answer any of these questions or maybe have an idea how to solve any of this (or know how much RAM the PSP has)

Luke

I would just send the whole thing as a C string (using sprintf). Simple to do and much easier to debug.

What do you mean as a C string? Of course it's a string that I send, but it needs to be formatted so that I can make a data-structure out of it which I can use to navigate through the music
-= Double Post =-
WTF! I read the PSP only has 8 MB of RAM!?!!! That is bull****! My webcam has more RAM than this! I will need to store the artist- and album-data in a file. Is there really no way to serialize/unserialize data-structures? Or maybe a small lightweight DB for the PSP?

Not sure if it supports serialization without extra code... but at a quick glance I like PHP's serialization model, as bulky as it is. Check it out here.

As for the lightweight DB... maybe store a hash map/table in a file. Dunno.

Uhhh... the PSP has 32MB of RAM of which 24MB are available to user-mode applications. That should be far enough for your needs (even 8MB should suffice). Read the wiki on ps2dev.org for more information on the PSP's specs.
And sending data shouldn't get overcomplicated and stay as simple as possible unless you need to decypher the data in multiple applications (like just providing a server application). In your case, I'd just send the raw data connected by spacing chars (s.th. like '$' or '%' that isn't used inside normal text) and have a fixed order of data, e.g. first comes artist name, then the artists albums terminated by another special character, then the next artist etc. until one (or two) zero byte(s) is sent to terminate the whole list. Pretty much like your "propietary" format, just more or less readable and no need for the extra transfer of list lengths.

PS: A list of ~500 artists with lets say ~30 albums on average and a album title length of ~50 average would take 750000 bytes, and still only 775000 bytes with each artists name also ~50 chars long on average (which is pretty exaggerated everywhere). That's still less than one MB, so I there really is not the smallest problem with RAM usage (even with overhead taken into account). You should learn to get an idea of the memory usage of your datas.

The PSP has 32mb of RAM.
I would just keep the whole thing simple. Lets say the data I want to send are:
- Song name
- Artist name
- Track length

I would construct a C string like:
$SongName:Blah Name|ArtistName:More Blah Name|TrackLength:34

$ designates the start of a new data record, | is the delimiter for a for the data member. The symbols can easily be replaced by non typable ASCII values. This then would be parsed by the reciever very easily.

C string is a char array, I normally use C++ which has a string class as part of the STL.

What do I need to get started developing on the psp. If you dont want to put links then thats kewl I just need the names.
Like I think you need
cygwin and the psp tool chain. Is that all?
And cant I just use my compiler (Dev C++) or does it have to be cygwin? or is it just easier to use cygwin?

Go to ps2dev.org forums, psp-software development section, read the sticky (Dev C++).
Go to psp-programming forums, read the stickies (setting up cygwin+toolchain [might be covered in the ps2dev sticky already]).
Good luck!

Probably a RAW file converted using bin2o.

The conversion is all done in the makefile. Quite a few of the SDK samples in /samples/gu/ use this method, check them out.

It compiles fine but when I press Up or Down My Megaman Sprite doesnt move and it freezes or something when i try to go back to the XMB (by pressing the Home button and accepting to "Yes")

Remove the return call in the loop, return makes it basically quit out of hte current function and return whatever you secify (so anything using main's return value would get 1or0 or w/e you put it in..). Just place the return call OUT of the while loop. Note, you cant simply remove it as all integers return a value... main applies.

Insomniac - But the unsgined char array can be seen within the snakman source, meaning it was converted and added manially... Does bin2o spit out the unsigned char array? And whats that link to using them (i know how) but it explained exactly how to get your image embedded... grr...

Ok SG57.

Imagine your file is named image.raw, you link it in your OBJS line in the makefiles as image.o.

You then have a line like this in your makefile:

Code:

---

image.o : image.raw
        bin2o -i image.raw image.o image

---

Then in your actual code you link to it like such:

Code:

---

extern unsigned char image_start[];

---

Note the '_start'. bin2o will name the converted image like this.

Insomniac - You're still not understanding me... Look at the snakeman source. Youll see a very large unsgined char array called background. They DIDNT use bin2o unless it has an option to export it into an unsigned char array. Im gonna try it though, but my own variation...

That reminds me of the what you have to do with the GBA when I was (attempting) developing on it a few years back.

It is basically taking the image and converting it to a cahr array as you said. Depending on what format you want the image in, it can be just one entry per pixel with each entry representing the RGB value. Or it can be the asscioated palette entry.

I got a quick question for you guys; How do you implent a command into the makefile so it wont generate a param.sfo and a .elf file? just adding the regular rm- stuff doesn't seem to work.

It's probably bin2c then.

My way works without complicating your source code with the full array.

Help..
