SetProcPermissions (Windows Embedded CE 6.0)
This function sets the internal permissions bit mask for the current thread, thereby enabling access to the address space of another process.
This function is no longer supported as of CE 6.0.
Typically, a driver saves the permissions of a calling process, and then sets the driver's thread permissions to include the calling process when needed. After the work for the calling process is complete, the driver's thread permissions are reset. Setting process permissions to 0xFFFFFFFF should be used sparingly because it enables access to all of the virtual address spaces.
