Thread safety
 

Hello everyone,

I was wondering if there is a list somewhere of the functions
that are not thread safe under gcc.

regards,
John

Google

and all will be revealed.

Hope this helps.

If I am not mistaken, there are a few functions in the libc which are not thread safe and those are clearly indicated in the GNU libc manual. There are not many of them if I remeber well.

jlinkels

lots of times there are thread safe versions hidden in there as well see
#define _REENTRANT
strtok_r
etc

important to remember
the POSIX/SUSv3 standard developers indicate that atomicity for socket I/O is "unspecified".

its not a bad idea to always do you own serialization.
