23 * SemThread Manager.
24 *
25 * This module manages semaphores through its proxy ISemThreadSupport
26 * interface. It has a module wide config parameter
27 * {@link #Proxy} which needs to be bound to an OS specific delegate before
28 * this module can be used.
29 *
30 * Here is an example showing how the proxy is bound to an BIOS 6.x specific
31 * delegate.
32 *
33 * @p(code) 34 * var SemThread = xdc.useModule('xdc.runtime.knl.SemThread');
35 * SemThread.Proxy = xdc.useModule('ti.sysbios.xdcruntime.SemThreadSupport');
36 * @p 37 *
38 * Typically the package containing the delegates have a Settings module that
39 * will bind all {@link xdc.runtime.knl} proxies. The following
40 * example sets up all the xdc.runtime.knl proxies.
41 *
42 * @p(code) 43 * xdc.useModule("ti.sysbios.xdcruntime.Settings");
