DPNS_GETCWD(3)
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.
- ENSNACT Name server is not running or is being shutdown.
