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.

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.
