• File src/runtime/threading.m — part of check-in [ef6d69931e] at 2019-02-07 00:46:41 on branch trunk — Make style consistent between ObjFW and ObjFW_RT

  ObjFW_RT used to be a separate project that followed the BSD style, as
  it was written in pure C, while ObjFW's style is based on the BSD style
  with changes to make it a better fit for Objective-C. This commit
  changes ObjFW_RT to use the same style as ObjFW. (user: js, size: 1205) [annotate] [blame] [check-ins using]
