void jit_error_sym	(	void *	x,

void jit_global_critical_enter ( void )

Enters the global Jitter critical region.

This function is useful for simple protection of thread sensitive operations. However, it may be too broad a lock, as it prevents any other operations that use the global critical region from working. For more localized control, I would suggest using either Max's systhread API or the platform specific locking mechanisms however, be sensitive to the possibility deadlock when locking code which calls code which may require the locking off unknown resources.
