cat_poll - poll for data on file descriptors
#include <cat.h>
int cat_poll(cat_session *session, int fd_ids, int mseconds);
Waits for mseconds, a number of milliseconds, or until data is present on any of the
descriptors indicated by fd_ids of the session. File descriptors are bit values that may be logically ORed
together to produce a set of descriptors.
If mseconds is negative, cat_poll() will wait indefinitely.
Returns the set of all descriptors where data is available, 0 on timeout,
or a negative code on error.
