lfc_readdirg caches a variable number of such entries, depending on the filename size, to minimize the number of requests to the name server.
As lfc_readdirg returns a null pointer both at the end of the directory and on error, an application wishing to check for error situations should set serrno to 0, then call lfc_readdirg, then check serrno and if it is non-zero, assume an error has occurred.
