Status changed from Open to Rejected Assignee set to ko1 (Koichi Sasada) Maybe you want to use it for CV to make it fast. However, we are not recommend CV because it is difficult primitive. So we shouldn't touch it. ---------------------------------------- Feature #8882: rb_obj_is_mutex() into include/ruby/intern.h https://bugs.ruby-lang.org/issues/8882#change-42149 Author: Glass_saga (Masaki Matsushita) Status: Rejected Priority: Normal Assignee: ko1 (Koichi Sasada) Category: Target version: current: 2.1.0 rb_obj_is_mutex() is currently an internal API function. However, this function is useful for C extension developers to distinguish between Mutex and other objects extended by Mutex_m. I want to use it in ext/thread/thread.c for this purpose. -- http://bugs.ruby-lang.org/
