Directory Checking Code

[pspfreak9]

I want code that checks for a dir. then apply a functions due to the availability of that dir.
How about somethin like this:

if dir {
(dirc name) then
(function)
    }else{
(function)
}

see I am not sure about the:

if dir {

If somebody could give me code to replace that part...
THX in advancs

I changed it

[psphacker12.]

I found this

#include <errno.h>
#include <dirent.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
 DIR *pdir;
 struct dirent *pent;

 pdir=opendir("."); //"." refers to the current dir
 if (!pdir){
 printf ("opendir() failure; terminating");
 exit(1);
 }
 errno=0;
 while ((pent=readdir(pdir))){
  printf("%s", pent->d_name);
 }
 if (errno){
 printf ("readdir() failure; terminating");
 exit(1);
 }
 closedir(pdir);
}

GOOOOOGLE POWAH

But how do I put that In the IF function
Cuase I dont want to open the dic If it finds the dirc then it does the function
It is to make sure my app has all nessecry files when some one runs

Just use the functions to open directories/files and check the return values from them.

Use opendir for directories and fopen for files.

pdir=opendir("thedir");
 if(pdir == NULL)
 printf ("Directory doesn't exist...");

FILE *fp = fopen("somefile.txt", "r");
if(fp == NULL)
printf("File doesn't exist...");

In English please?!

You open the dir to check if if the return value is 0 then it's not there.
Then you know wether it's there or not, then you can do with the dir whatever you want

[pspfreak9]

But what if pdir is true (there) how do i make a IF function from that??

Can someone help me please

Come on

Ooh, if statements are SOOOO complicated.^^

if(pdir != NULL)
{
    function1();
}

[pspfreak9]

no no no

your code is if it is == to NULL
But what if it checks for the dirc then if it finds the dirc (the dirc is on the MS) then it does a function. what you are doing is when the dirc isnt there

[psphacker12.]

if(pdir != NULL)
{
    function1();
}

== true
!= false

[pspfreak9]

again that is false:

!= false

psphacker12: That is incorrect:
== means "is equal to"
!= means "is not equal to"

Taking the previous code:

FILE *fp = fopen("somefile.txt", "r");
if(fp == NULL)
{
    printf("File doesn't exist...");
}
else
{
    // Put code here is the file does exist
}
