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¶

ENOMEM

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

EINVAL
