Description

Obtains the ID of the current process.

This API has been adapted to the physical machine and VM scenarios when obtaining the process ID. You only need to call it to obtain the process ID and then use it with other APIs (see aclrtMemExportToShareableHandle for details) to share the physical memory. If you obtain the process ID without calling this API, an exception may occur when you use the process ID.
