NAME

lfc_creat - create a new LFC file or reset it in the name server  

SYNOPSIS

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

int lfc_creat (const char *path, mode_t mode)

int lfc_creatx (const char *path, mode_t mode, struct lfc_fileid *file_uniqueid)  

DESCRIPTION

lfc_creat creates a new LFC file 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)).

lfc_creatx behaves in the same way and returns the file unique id (name server hostname and file id).

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 and 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.
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
