There is not need
for {
EvChan := robotgo.EventStart()
}
because event start is event channel.
Thank you for your answer. The above is the test code. I created a thread in C language and called robogo. EventStart() and robogo. EventEnd() many times, but when I called robogo. Eventend() several times, errors like the above will appear. Do you have any good solutions？
`IOHOOK_API int hook_stop() { int status = IOHOOK_FAILURE; if (hook != NULL && hook->ctrl.display != NULL && hook->ctrl.context != 0) { // We need to make sure the context is still valid. XRecordState *state = malloc(sizeof(XRecordState)); if (state != NULL) { if (XRecordGetContext(hook->ctrl.display, hook->ctrl.context, &state) != 0) { // Try to exit the thread naturally. if (state->enabled && XRecordDisableContext(hook->ctrl.display, hook->ctrl.context) != 0) { #ifdef USE_XRECORD_ASYNC pthread_mutex_lock(&hook_xrecord_mutex); running = false; pthread_cond_signal(&hook_xrecord_cond); pthread_mutex_unlock(&hook_xrecord_mutex); #endif
// See Bug 42356 for more information.
// https://bugs.freedesktop.org/show_bug.cgi?id=42356#c4
//XFlush(hook->ctrl.display);
XSync(hook->ctrl.display, False);
if (hook->ctrl.display) {
XCloseDisplay(hook->ctrl.display);
hook->ctrl.display = NULL;
}
status = IOHOOK_SUCCESS;
}
} else {
logger(LOG_LEVEL_ERROR, "%s [%u]: XRecordGetContext failure!\n",
__FUNCTION__, __LINE__);
status = IOHOOK_ERROR_X_RECORD_GET_CONTEXT;
}
free(state);
} else {
logger(LOG_LEVEL_ERROR, "%s [%u]: Failed to allocate memory for XRecordState!\n",
__FUNCTION__, __LINE__);
status = IOHOOK_ERROR_OUT_OF_MEMORY;
}
return status;
}
logger(LOG_LEVEL_DEBUG, "%s [%u]: Status: %#X.\n",
__FUNCTION__, __LINE__, status);
return status;
}`
It always breaks in here. // See Bug 42356 for more information. // https://bugs.freedesktop.org/show_bug.cgi?id=42356#c4 //XFlush(hook->ctrl.display); XSync(hook->ctrl.display, False); if (hook->ctrl.display) { XCloseDisplay(hook->ctrl.display); hook->ctrl.display = NULL; } what should I do to prevent breaking when i called start() and end() many times.
Emm, I will test it on Ubuntu, this is X11 threaded bug. It work good on the macos.
