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.

NAME

       dpns_readdirx - read DPNS directory opened by dpns_opendir in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       struct dpns_direnstat *dpns_readdirx (dpns_DIR *dirp)

DESCRIPTION

       dpns_readdirx reads the DPNS directory opened by dpns_opendir in the name server.  This routine returns a pointer to a structure containing
       the current directory entry including the stat information.  dpns_readdirx caches a variable number of such entries, depending on the file-
       name size, to minimize the number of requests to the name server.

       dirp   specifies the pointer value returned by dpns_opendir.

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. When the end of the directory is encountered, serrno is not changed. If the operation
       failed, serrno is set appropriately.

       As dpns_readdirx returns a null pointer both at the end of the directory and on error, an application wishing to check for error situations
       should set serrno to 0, then call dpns_readdirx, then check serrno and if it is non-zero, assume an error has occurred.

ERRORS

       EBADF	    File descriptor in DIR structure is invalid.

       EFAULT	    dirp is a NULL pointer.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
