Get file list from a directory by name in c

[omeraygor]

hi
i try to get file names listed by date or name in c. How can i do this.
there is a code: But this gives randomly file names.

DIR *dir;
struct dirent *ent;
    dir = opendir ("c:\\src\\");
if (dir != NULL) {
 
  /* print all the files and directories within directory */
  while ((ent = readdir (dir)) != NULL) {
    printf ("%s\n", ent->d_name);
  }
  closedir (dir);
} else {
  /* could not open directory */
  perror ("");
  return EXIT_FAILURE;
}

This code:

while ((ent = readdir (dir)) != NULL) { etc...

may be better this way:

while ((ent = readdir (dir)) != false) {

readdir returns a boolean of true or false. NULL is specifically a 0.

If readdir returns a boolean then that return value cannot also be used as a pointer to a dirent structure. @weaknessforcats: you're probably thinking of readdir_f.

opendir and readdir are not part of the Standard C Library. I assume you are using POSIX, but it is possible that you're using some other library that has different behavior than POSIX. Where are you getting these functions?
