C++ (Cpp) svc_unmapMemoryBlock Examples

Example #1

File: main.c Project: Tybus/3Dfrogr

void gspGpuExit()
{
	GSPGPU_UnregisterInterruptRelayQueue(NULL);

	//unmap GSP shared mem
	svc_unmapMemoryBlock(gspSharedMemHandle, 0x10002000);
	svc_closeHandle(gspSharedMemHandle);
	svc_closeHandle(gspEvent);

	gspExit();

	//free GSP heap
	svc_controlMemory((u32*)&gspHeap, (u32)gspHeap, 0x0, 0x2000000, MEMOP_FREE, 0x0);
}

Example #2

File: HID.c Project: namidairo/ctrulib

void hidExit()
{
	svc_unmapMemoryBlock(hidMemHandle, (u32)hidSharedMem);
	svc_closeHandle(hidMemHandle);
	svc_closeHandle(hidHandle);
}
