How to use SIGRTMIN in x86 or armeabi-v7a abi in Android NDK?
0
I am trying to use SIGRTMIN signal to create blocking signalhandler in Android NDK.
int startThread(){
pthread_t thread;
sigset_t set;
/* Block SIGRTMIN other threads created by main()
will inherit a copy of the signal mask. */
sigemptyset(&set);
int rc = sigaddset(&set, SIGRTMIN);
__android_log_print(ANDROID_LOG_DEBUG, "LOG", "Return Code:%d",rc);
__android_log_print(ANDROID_LOG_DEBUG, "LOG", "Error Code:%d",errno);
pthread_sigmask(SIG_BLOCK, &set, NULL);
pthread_create(&thread, NULL, &sig_thread, (void *) &set);
}
static void *sig_thread(void *arg)
{
sigset_t *set = arg;
int s, sig;
for (;;) {
s = sigwait(set, &sig);
__android_log_print(ANDROID_LOG_DEBUG, "LOG", "Signal handling thread got signal %dn", sig);
}
}
I am getting Return Code as -1 and Error code as 22 (EINVAL - Invalid Argument) while adding signal set sigaddset(&set, SIGRTMIN)
This is happening in x86 or armeabi-v7a abi. If i use x86_64 then it works.
is there any way to solve this problem or any alternative in x86/armeabi-v7a abi in Android?

Are you using an old NDK by any chance?SIGRTMINused to be a constant that would get baked into your application that wouldn't necessarily be correct on new versions of Android. It's since been changed to be a function (with an as correct as possible fallback for pre-L API levels), but if you're using an old NDK it's possible that you have a bad definition ofSIGRTMINfor your device.
