| * ======== SemProcess ======== |
| * SemProcess Manager |
| * |
| * This module manages multi-process semaphores through its proxy |
| * ISemProcessSupport interface. It has a module wide config parameter |
| * {@link #Proxy} which needs to be bound to an OS specific delegate before |
| * this module can be used. |
| * |
| * Here is an example showing how the proxy is bound to an BIOS 6.x specific |
| * delegate. |
| * |
| * @p(code) |
| * var SemProcess = xdc.useModule('xdc.runtime.knl.SemProcess'); |
| * SemProcess.Proxy = xdc.useModule('ti.sysbios.xdcruntime.SemProcessSupport'); |
| * @p |
| * |
| * Typically the package containing the delegates have a Settings module that |
| * will bind all {@link xdc.runtime.knl} proxies. The following |
| * example sets up all the xdc.runtime.knl proxies. |
| * |
| * @p(code) |
| * xdc.useModule("ti.sysbios.xdcruntime.Settings"); |
