i try to search txt file in a folder

my code


Generic Code:

int searchfile(char *dir, char *filename, int flength, char *ext)
{
DIR *pdir;
pdir = opendir(dir);
struct dirent *pent;
if (!pdir)
{
printf ("%s - Incapable d'utiliser opendir()\n", strerror
(errno));
return 1;
}

while((pent = readdir(pdir)) != NULL)
{
if(strcmp(pent->d_name + flength, ext) == 0)
{
printf("%s\n", pent->d_name);
}
}
closedir(pdir);
return 0;
}


i call this function with

Generic Code:

searchfile(local_dir_led,"", 28, ".txt");



all my file name are the same size... but will not be true soon
how to do it when the file name size are not the same?

i would like to put the file name in a list....
what is the better way to do it?

Instead of passing flength as a parameter, compute it:

flength = strlen(pent->d_name) - strlen(ext);

If flength < 0 then the filename is shorter than the extension, so skip
this file.
