Typedef Documentation

MTX_OPTIONS_M

Typedef for enum _MTX_OPTIONS_M.

Warning:

Almost no POSIX implementations support any kind of deterministic behaviour when multiple threads are trying to lock the same mutex. It is therefore not portable to architect a program which depends on the pending strategy. It may be used as an optimization strategy on those platforms that support it.
