RFIO_READDIR(3) 					      Rfio Library Functions						   RFIO_READDIR(3)

NAME
       rfio_readdir - read directory opened by rfio_opendir

SYNOPSIS
       #include <sys/types.h>
       #include <dirent.h>
       #include "rfio_api.h"

       struct dirent *rfio_readdir (RDIR *dirp);

DESCRIPTION
       rfio_readdir  reads  the  directory opened by rfio_opendir.  This routine returns a pointer to a structure containing the current directory
       entry.

       dirp   specifies the pointer value returned by rfio_opendir.

NOTES
       Only the fields d_name, d_reclen and on some platforms d_namlen are filled.  For LCG directories, a multi-threaded application will need to
       initialize  itself  the	Cthread  (LCG Thread Interface) library ; this is done by including "shift/Cthread_api.h" and calling the function
       Cthread_init() at the beginning. Otherwise accessing LCG directories will not be thread-safe. See Cthread(3).

RETURN VALUE
       This routine returns a pointer to a structure containing the current directory entry if the operation was successful or NULL if the end	of
       the directory was reached or if the operation failed. In the latter case, serrno is set appropriately.

ERRORS
       EBADF	    File descriptor in DIR structure is invalid.

       EFAULT	    dirp is a NULL pointer.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.
