Hi,.. I'm writing a multi-threaded application on solaris 8 using POSIX-threads, and I was wondering how MT-safe the STL library is. I found __STL_PTHREADS in <stl_alloc.h>, is this the only flag and thereby the right one to use ? Or are there other/more general flag(s) to use ? regards, Peter Zijlstra PS. is there proper documentation on this subject ?
