iom_wait(3) Library Functions Manual iom_wait(3) NAME iom_wait - wait for event from I/O multiplexer SYNTAX #include <libowfat/io.h> int iom_wait(iomux_t* c, int64* fd, unsigned int* events, unsigned long timeout); DESCRIPTION iom_wait will wait for events registered to the I/O multiplexer with iom_add. It will wait timeout milliseconds. If during that time any of the registered events occur, iom_wait will set fd to the file descriptor the event happened on, and events to the sum of IOM_READ, IOM_WRITE and IOM_ERROR, depending on what event actually hap- pened, and return 1. If nothing happens during that time, it will return 0 and leave fd and events alone. Note that the event registration is removed from the iomux_t context if it occurs. You will have to call iom_wait again after you handled the event, if you are still interested in it. Closing a file descriptor with registered events will discard the event registration. LINKING You may have to add -lpthread to the command line in the linking step. RETURN VALUE iom_wait returns 1 on success, 0 if there was a timeout, and -1 on error, setting errno. If iom_abort was called on the I/O multiplexer context, it will return -2. SEE ALSO iom_init, iom_add, iom_abort iom_wait(3)
