Writing User-stream Post-hooks

The user-stream post-hook is, if defined, called after all the streams have been defined, once for each of the three standard streams. It has a slightly different prototype:

void user_stream_post_hook(int which, SP_stream *str)

where str is a pointer to the corresponding SP_stream structure. There are no requirements as to what this hook must do; the default behavior is to do nothing at all.

The post-hook is intended to be used to do things that may require that all streams have been created.
