NAME
lfc_opendirg - open a LFC directory, having the specified GUID, in the
name server
SYNOPSIS
#include <sys/types.h> #include "lfc_api.h" lfc_DIR *lfc_opendirg (const char *path, const char *guid) lfc_DIR *lfc_opendirxg (char *server, const char *path, const char *guid)
DESCRIPTION
lfc_opendirg opens a LFC directory, having the specified GUID, in the
name server to be used in subsequent lfc_readdirg operations. A
lfc_DIR structure and a buffer to cache the directory entries are allocated in the client API.
guid specifies the Grid Unique IDentifier.
- path specifies the logical pathname relative to the current LFC
- directory or the full LFC pathname.
RETURN VALUE
This routine returns a pointer to be used in the subsequent directory
function calls if the operation was successful or NULL if the operation
failed. In the latter case, serrno is set appropriately.
ERRORS
- ENOENT A component of path prefix does not exist or path is a
- null pathname.
- EACCES Search permission is denied on a component of the path
- prefix or read permission is denied on path.
- EFAULT path is a NULL pointer.
- EINVAL The length of the guid component exceeds CA_MAXGUIDLEN.
- ENOTDIR A component of path prefix is not a directory.
- ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of
- a path component exceeds CA_MAXNAMELEN.
- SENOSHOST Host unknown.
