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 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.
