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 latter 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.
