[PATCH 1/3] jackaudio: use ifdefs to hide unavailable functions |
Date: |
Sun, 26 Dec 2021 16:40:15 +0100 |
On Windows the jack_set_thread_creator() function and on MacOS the
pthread_setname_np() function with a thread pointer paramater is
not available. Use #ifdefs to remove the jack_set_thread_creator()
function call and the qjack_thread_creator() function in both
cases.
The qjack_thread_creator() function just sets the name of the
created thread for debugging purposes and isn't really necessary.
>From the jack_set_thread_creator() documentation:
(...)
No normal application/client should consider calling this. (...)
