Subject cvs commit: apache/src alloc.c http_main.c multithread.h
Date Mon, 16 Jun 1997 17:53:16 GMT
dgaudet     97/06/16 10:53:15

  Modified:    src       alloc.c http_main.c multithread.h
  Log:
  Fix the null statement warnings in a manner that avoids hassles should
  anyone start checking the return values.  Also fix create_mutex() in the
  non-multithreaded case in preparation for someone checking the return
  values in the multithreaded case.  HINT HINT.  I would have started checking
  the values except I'm not totally sure what to do to report errors.
