Subject: Update: f_thread_lock_read() should return F_resource_not.
X-Git-Tag: 0.5.3~47
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=37c81843b69abe01813652f19b3480afdb1a7669;p=fll

Update: f_thread_lock_read() should return F_resource_not.

The pthread_rwlock_rdlock() potentially returns EAGAIN.
This needs to be handled, translated into F_resource_not (with error bit), and then returned.
