Thread-Safe libc

Fedele Giuseppe — Mon, 18 May 2009 10:00:21 GMT

Hello,

I'm starting developing a C multi-thread application on HP-UX 11.31 platform.

I know there are libc routines that are "non reentrant", that have a reentrant interface having "_r" suffix.

My question is: which is the list of "non reentrant" routines in HA-UX 11.31?
Is there any document dealing whit them?

Many thanks

Giuseppe Fedele

See the list in thread_safety(5). Generally, all libc routines are reentrant, even if they don't have _r.

If you are compiling with HP's compilers, make sure you use -mt.
