NAME¶
lfc_getcwd - get LFC current directory used by the name server
SYNOPSIS¶
#include <sys/types.h>
#include "lfc_api.h"
char *lfc_getcwd (char *buf, int size)
DESCRIPTION¶
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.
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

- SECOMERR
- Communication error.
