NAME
lfc_readdirxc - read LFC directory opened by lfc_opendir in the name
server
SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
struct lfc_direnstatc *lfc_readdirxc (lfc_DIR *dirp)
DESCRIPTION
lfc_readdirxc reads the LFC directory opened by lfc_opendir in the name
server. This routine returns a pointer to a structure containing the
current directory entry including the stat information and the comment
associated. lfc_readdirxc caches a variable number of such entries,
depending on the filename size, to minimize the number of requests to
the name server.
dirp specifies the pointer value returned by lfc_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 lfc_readdirxc 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 lfc_readdirxc, 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.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
