Directory functions


OK. First things first. These functions are NOT part of the ANSI standard library. They may not be supported on your platform.

Here is a quick summary of each Funktion, they are listed in the order in which you may want to execute them. opendir Open a directory stream. readdir read the current entry in the stream. scandir Find an entry in a direcory. seekdir Jump to a directory offset. telldir Return the current location within the directory stream. rewinddir Return to the start of the directory stream. closedir Close a directory.


Library:   dirent.h

Prototype: DIR *opendir(const char *name);

	   struct dirent *readdir(DIR *dir);

	   int scandir(const char *dir, struct dirent ***namelist,
               int (*select)(const struct dirent *),
               int (*compar)(const void *, const void *));
		
	   void seekdir(DIR *dir, off_t offset);

	   off_t telldir(DIR *dir);

	   void rewinddir(DIR *dir);

	   int closedir(DIR *dir);
	

The dirent structure does not seem to be documented in the man pages, so here it is.

	struct dirent 
	{
          long            d_ino;
       	  off_t           d_off;
       	  unsigned short  d_reclen;
       	  char            d_name[NAME_MAX+1];
	};
