XtToolkitThreadInitialize(3Xt)

     NAME
          XtToolkitThreadInitialize - initialize the toolkit for
          multiple threads

     SYNTAX
          Boolean XtToolkitThreadInitialize()

     DESCRIPTION
          If XtToolkitThreadInitialize was previously called, it
          returns. The application programmer must ensure that two or
          more threads do not simultaneously attempt to call
          XtToolkitThreadInitialize; the effect of this is undefined.
          XtToolkitThreadInitialize returns True if the host operating
          system has threads and the Intrinsics are thread safe.
