iom_init(3) Library Functions Manual iom_init(3) NAME iom_init - create new I/O multiplexer SYNTAX #include <libowfat/io.h> int iom_init(iomux_t* c); DESCRIPTION iom_init initializes an I/O multiplexer. An I/O multiplexer is a context that can be used to do I/O multiplexing with support for multiple threads. Add events to a multiplexer using iom_add, and then get the next available event with iom_wait. If you are done and want to signal all the threads something, set a volatile global variable to tell the threads to stop and then fall iom_abort to tell all pending iom_wait operations in all threads to return immediately. After iom_init is done, iom_add and iom_wait can be called from different threads on the same context, and they will synchronize internally. LINKING You may have to add -lpthread to the command line in the linking step. RETURN VALUE iom_init returns 0 on success and -1 on error, setting errno. SEE ALSO iom_add, iom_wait, iom_abort iom_init(3)
