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.

NAME

       dpns_readlink - read value of a symbolic link in the DPNS Name Server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_readlink (const char *path, char *buf, size_t bufsiz)

DESCRIPTION

       dpns_readlink reads the value of a symbolic link in the DPNS Name Server.

       path   specifies the link name relative to the current DPNS directory or the full DPNS pathname.

       buf    points at a buffer to receive the value.

       bufsiz gives the buffer size.

RETURN VALUE

       This  routine returns the number of characters put in the buffer if the operation was successful or -1 if the operation failed. In the lat-
       ter case, serrno is set appropriately.

ERRORS

       ENOENT	    The named link does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix.

       EFAULT	    path or buf is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    path is not a symbolic link.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
