NAME

       dpns_getcwd - get DPNS current directory used by the name server

SYNOPSIS

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

       char *dpns_getcwd (char *buf, int size)

DESCRIPTION

       dpns_getcwd  gets  the  DPNS current directory used by the name server.
       This current working directory is stored in a thread-safe  variable  in
       the client.

       If buf is not NULL, the current directory name will be stored there.
       If  buf  is  NULL,  dpns_getcwd  allocates a buffer of size bytes using
       malloc.

       size must be at least the length of the directory name to  be  returned
       plus one byte.

RETURN VALUE

       This routine returns buf if the operation was successful or NULL if the
       operation failed.  In the latter case, serrno is set appropriately.

ERRORS

       ENOENT       The current directory has not been set  yet  or  does  not
                    exist anymore.

       ENOMEM       buf is a NULL pointer and memory could not be allocated.

       EINVAL       size is less than or equal to zero.

       ERANGE       size  is  greater  than  0  and  less than size of current
                    directory name plus 1.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.
