- These are functions on bit arrays associated with file descriptors
- (sockets), for use with asynchronous input/output. They are used
- primarily for checking whether a file has pending input (not sure
- about output). They ought to be defined in <sys/types.h>. If you
- want to know more, a "man select" ought to be a bit more
- informative.
