Hi All,
Usually we use pthread_mutexattr_setpshared to share different
mutex with different process. But I have checked the bionic libc
implementation. It only support PTHREAD_PROCESS_PRIVATE setting.
Does it mean android does not support mutex shared between different
processes?
pthread.c in android/bionic/libc/bionic
772 int pthread_mutexattr_setpshared(pthread_mutexattr_t *attr, int
pshared)
773 {
774 if (!attr)
775 return EINVAL;
776
777 return (pshared == PTHREAD_PROCESS_PRIVATE) ? 0 : ENOTSUP;
778 }
Thanks
Guoyin Chen
