io_wait
io_wait(3) Library Functions Manual io_wait(3) NAME
io_wait - wait for events SYNTAX
#include <io.h> void io_wait(); DESCRIPTION
io_wait() checks the descriptors that the program is interested in to see whether any of them are ready. If none of them are ready, io_wait() tries to pause until one of them is ready, so that it does not take time away from other programs running on the same computer. io_wait pays attention to timeouts: if a descriptor reaches its timeout, and the program is interested in reading or writing that descrip- tor, io_wait will return promptly. Under some circumstances, io_wait will return even though no interesting descriptors are ready. Do not assume that a descriptor is ready merely because io_wait has returned. io_wait is not interrupted by the delivery of a signal. Programs that expect interruption are unreliable: they will block if the same sig- nal is delivered a moment before io_wait. The correct way to handle signals is with the self-pipe trick. SEE ALSO
