except for the extra parameter which can be one of these four values:

MULTITHREAD USAGE
Thread Safe: No
Cancel Safe: No
Fork Safe: No
Async-cancel Safe: No

These functions cannot 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 and before These functions should not
be called by a multithreaded application that support asynchronous can‐
cellation or asynchronous signals.
