XInitThreads(3X) XLIB FUNCTIONS XInitThreads(3X)
NAME
XInitThreads - initializes Xlib support for concurrent threads
SYNTAX
Status XInitThreads();
DESCRIPTION
The XInitThreads function initializes Xlib support for concurrent threads. This function must be the first Xlib function a multi-threaded
program calls, and it must complete before any other Xlib call is made. This function returns a nonzero status if initialization was suc-
cessful; otherwise, it returns zero. On systems that do not support threads, this function always returns zero.
It is only necessary to call this function if multiple threads might use Xlib concurrently. If all calls to Xlib functions are protected
by some other access mechanism (for example, a mutual exclusion lock in a toolkit or through explicit client programming), Xlib thread ini-
tialization is not required. It is recommended that single-threaded programs not call this function.
