是否有什么可以替换<ucontext.h>函数?

ucontext.h void *

int argc, ... makecontext makecontext(ucp, func, 1, (void *)arg);

https://computing.llnl.gov/tutorials/pthreads/#ConditionVariables

self->flag = 0;
other_thread->flag = 1;
pthread_mutex_lock(other_thread->mutex);
pthread_cond_signal(other_thread->cond);
pthread_mutex_unlock(other_thread->mutex);
pthread_mutex_lock(self->mutex);
while (!self->flag)
    pthread_cond_wait(self->cond, self->mutex);
pthread_mutex_unlock(self->mutex);

other_thread task_switch pthread_cond_wait pthread_cond_signal

Boost.Context recently accepted ucontext
