# XtToolkitThreadInitialize(3)

initialize the toolkit for multiple threads

## NAME

XtToolkitThreadInitialize - initialize the toolkit for multiple threads

## SYNTAX

\#include \<X11/Intrinsic.h\>

Boolean XtToolkitThreadInitialize(void);

## 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.
