NAME

       dpns_creat - create a new DPNS file or reset it in the name server

SYNOPSIS

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

       int dpns_creat (const char *path, mode_t mode)

       int dpns_creatx (const char *path, mode_t mode, struct dpns_fileid *file_uniqueid)

DESCRIPTION

       dpns_creat creates a new DPNS 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 dpns_umask(3)).

       dpns_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 DPNS directory or  the  full
              DPNS 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     Communication error.

       ENSNACT      Name server is not running or is being shutdown.
