Hi,
You don't need to create thread, just register your thread into pjlib
because the thread already created by external.
I wrote a DLL library using pjmedia. This dll will export c functions.
Becaue high level GUI programmer which call my DLL don't handle thread
carefully, they event don't know when they will create thread. So I
put code which like Manjeet provided into every exported function calls.
typedef struct external_thread
{
pj_thread_desc desc;
pj_thread_t *thread;
} external_thread;
std::list<external_thread *> e_threads;
void exported_func()
{
// register external thread into pjlib first, like Manjeet
provided.
}
regards,
Gang
