The XInitThreads(3X11) function is used to check the MT-safeness of
the Xlib. For a example, prepare a simple test program:
#include <stdio.h>
#include <X11/Xlib.h>
int main()
{
Display *d = XOpenDisplay(NULL);
int status;
status = XInitThreads();
printf("%d\n", status);
XCloseDisplay(d);
exit(status);
}
as xinitthreads.c and compile it as follows.
% cc -D_THREAD_SAFE -D_REENTRANT -I/usr/X11R6/include xinitthreads.c \
-L/usr/X11R6/lib -lX11 -pthread
If running ./a.out prints a non-zero number, your Xlibs are MT-safe.
