Re: Reentrant functions and memory allocation

I'm trying to put some old code in a portable, cross-platform

platform-independent way to write a reentrant function that
allocate dynamic memory? In other words: is it safe to use
malloc() or free() in a thread-safe function?

No. Because the malloc system will be operating on it's own memory
areas, and is not re-entrant. You have to ensure that all accesses
to the malloc package are done through appropriate guards.
