LFC_READLINK(3) 					       LFC Library Functions						   LFC_READLINK(3)

NAME

       lfc_readlink - read value of a symbolic link in the LFC Name Server

SYNOPSIS

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

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

DESCRIPTION

       lfc_readlink reads the value of a symbolic link in the LFC Name Server.

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

NAME

       lfc_opendir - open a LFC directory in the name server

SYNOPSIS

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

       lfc_DIR *lfc_opendir (const char *path)

DESCRIPTION

       lfc_opendir  opens a LFC directory in the name server to be used in subsequent lfc_readdir operations.  A lfc_DIR structure and a buffer to
       cache the directory entries are allocated in the client API.

       path   specifies the logical pathname relative to the current LFC directory or the full LFC pathname.

RETURN VALUE

       This routine returns a pointer to be used in the subsequent directory function calls if the operation was successful or NULL if the  opera-
       tion failed. In the latter case, serrno is set appropriately.

ERRORS

       ENOENT	    A component of path prefix does not exist or path is a null pathname.

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

       EFAULT	    path is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       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.
