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.
