lfc_mkdir

LFC_MKDIR(3)						       LFC Library Functions						      LFC_MKDIR(3)

NAME

       lfc_mkdir - create a new LFC directory in the name server

SYNOPSIS

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

       int lfc_mkdir (const char *path, mode_t mode)

DESCRIPTION

       lfc_mkdir creates a new LFC directory in the name server.

       An  entry  is created in the name server database and the directory's owner ID is set to the effective user ID of the requestor.  The group
       ID of the directory 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 directory are taken from mode, then all bits set in the requestor's file mode creation mask are cleared
       (see lfc_umask(3)).  The S_ISGID, S_ISUID and S_ISVTX bits are silently cleared.

       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 write permission on the parent directory is denied.

       EFAULT	    path is a NULL pointer.

       EEXIST	    path exists already.

       ENOTDIR	    A component of path prefix is not a directory.

       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.
