Dirent.h

dirent.h is the header in the C POSIX library for the C programming language that contains constructs that facilitate directory traversing. The function is not part of the C standard, but is considered "pseudo-standard" and is reliably portable between platforms.

Member types

Data types defined in the dirent.h header include:
* DIR - A structure representing a directory stream. Contains the following members::* struct _finddata_t dd_dta - disk transfer area:* struct dirent dd_dir - dirent structure:* long dd_handle:* int dd_stat - status of search: 0 = not started yet, -1 = off the end, positive = 0-based index of next entry

* struct dirent - A structure with the following members::* off_t d_off - not in all implementations:* unsigned short d_namlen - Length of name in d_name:* unsigned short d_reclen:* ino_t d_ino - file serial number:* char d_name [] - name of entry (will not exceed a size of NAME_MAX)

A short example of dirent.h usage is:
char **files=NULL;
void GetAllFiles(char *path, char*** files)
{
DIR *dir = opendir(path);
struct dirent *dp;
int i=0, j=0;
char *tmp;

while ((dp=readdir(dir)) != NULL)
{
i++; //counting number of files in directory (files+dirs)
}
rewinddir(dir);
(*files) = (char **)malloc(i*sizeof(char*));
while ((dp=readdir(dir)) != NULL)
{
(**files) = strdup(dp->d_name);
printf("%s ",dp->d_name);
(*files)++;
i++;
}
closedir(dir);
}
