Do I have to use thread safety if my GDK layer uses threads?

["Brian J. Murrell" <gtk-list-in interlinx bc ca>]

Hello,

I am writing a GTK+ 2.0 application using the DirectFB GDK layer.
DirectFB is multi-threaded (the GTK program itself runs in the initial
thread).  Does that mean that I need to write my GTK+ application in a
"thread safe" manner?

The reason I ask is that I came across a problem with my application.
At the start of my application I call:

  gtk_init (&argc, &argv);

and gtk_init() does a "bindtextdomain()" and my application is
getting suspended at gtk's call to "bindtextdomain()" with:

3346  rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
3346  rt_sigsuspend([] <unfinished ...>

I am assuming that this is an issue with threading and non-safe use of
data and tried getting rid of the bindtextdomain() call in gtk's
gtk_init() function and everything seemed to work fine again.

I am at a loss to figure out what the unsafe data access is however
and how to guard it.

Any ideas?

b.
