These functions can be called safely in a multithreaded environment.
They may be cancellation points in that they call functions that are
cancel points.
In a multithreaded environment, these functions are
not safe to be called by a child process after
fork()
and before
exec().
These functions should not be called by a multithreaded application
that supports asynchronous cancellation or asynchronous signals.
