Get lfc current directory used by the name server
#include <sys/types.h>
#include "lfc_api.h"
char *lfc_getcwd (char *buf, int size)
lfc_getcwd gets the LFC 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, lfc_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.
This routine returns buf if the operation was successful or NULL if the operation failed. In the latter case, serrno is set appropriately.
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.
ENSNACT
Name server is not running or is being shutdown.
