lfc_readlink - read value of a symbolic link in the LFC Name Server
int lfc_readlink (const char *path, char *buf, size_t bufsiz)
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.
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.
ENOENT The named link does not exist or is a null pathname.
EACCES Search permission is denied on a component of the path
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.
