: Would anyone please point me to a list of reentrant GNU C/C++ library
: functions? I have searched a lot on the web for it but without any
: success. Man page of signal(2) has listed system calls (POSIX
: 1003.1-2003 list) which are safe(reentrant) but thats not sufficient
: for my purpose.

: Thanks in advance.
Regarding the GNU implementation, you should ask on a dedicated
forum (clc++ is dedicated to the standard C++ language).
The C++ standards says nothing about multi-threaded or multi-
process platforms, so it is all platform-specific.
This said, on all major platforms, fully reentrant
implementations of the standard library are available.
This will usually be the case of GNU C/C++ as well,
although single-threaded libs (e.g. for malloc etc)
may also exist on some platforms.
Some standard C functions are known to be incompatible
with a reentrant implementation, because they use
static storage. These include strtok and gmtime, and
some functions altering the 'locale' settings.
Those calls can usually be avoided (or, occasionally,
accessed serially only by locking an associated mutex).
However, this requires using platform-specific techniques.
