NAME
lfc_creatg - create a new LFC file with the specified GUID or reset it
in the name server
SYNOPSIS
#include <sys/types.h>
#include "lfc_api.h"
int lfc_creatg (const char *path, const char *guid, mode_t mode)
DESCRIPTION
lfc_creatg creates a new LFC file with the specified GUID or resets it
in the name server.
If the file exists, the length is truncated to 0 and the mode and owner
are unchanged.
If the file does not exist yet, an entry is created in the name server
database and the file’s owner ID is set to the effective user ID of the
requestor. The group ID of the file is set to the effective group ID
of the requestor or is taken from the parent directory if the latter
has the S_ISGID bit set.
The access permission bits for the file are taken from mode, then all
bits set in the requestor’s file mode creation mask are cleared (see
lfc_umask(3)).
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 0 if the operation was successful or -1 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 the file does not exist and write permission on
the parent directory is denied or the file exists and
write permission on the file itself is denied.
EFAULT path or file_uniqueid is a NULL pointer.
EEXIST File exists already with a different GUID or has replicas.
ENOTDIR A component of path prefix is not a directory.
EISDIR path is an existing directory.
EINVAL The fileclass in the parent directory is zero or the
length of the guid exceeds CA_MAXGUIDLEN.
ENOSPC The name server database is full.
ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of
a path component exceeds CA_MAXNAMELEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
