NAME

yield - yields CPU to other coroutines

SYNOPSIS

#include <libdill.h>
int yield(void);
    

DESCRIPTION

By calling this function, you give other coroutines a chance to run.

You should consider using yield when doing lengthy computations which don't have natural coroutine switching points such as socket or channel operations or msleep.

RETURN VALUE

In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below.

ERRORS

•

ECANCELED: Current coroutine was canceled.

EXAMPLE

for(i = 0; i != 1000000; ++i) {
    expensive_computation();
    yield(); /* Give other coroutines a chance to run. */
}
