.SH "DESCRIPTION"
.sp
The zmutex class provides a portable wrapper for mutexes\&. Please do not use this class to do multi\-threading\&. It is for the rare case where you absolutely need thread\-safe global state\&. This should happen in system code only\&. DO NOT USE THIS TO SHARE SOCKETS BETWEEN THREADS, OR DARK THINGS WILL HAPPEN TO YOUR CODE\&.
.sp
Please add @discuss section in \&.\&./src/zmutex\&.c\&.
