       lfc_creatg  - create a new LFC file with the specified GUID or reset it
       in the name server


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

       int lfc_creatg (const char *path,  const char *guid, mode_t mode)


       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

       guid   specifies the Grid Unique IDentifier.

       path   specifies the logical  pathname  relative  to  the  current  LFC
              directory or the full LFC pathname.


       This  routine  returns  0  if the operation was successful or -1 if the
       operation failed. In the latter case, serrno is set appropriately.


       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.
