Frees a block of memory allocated by the unmanaged COM task memory allocator.
public static void FreeCoTaskMem(
- Type: System.IntPtr
The address of the memory to be freed.
You can use FreeCoTaskMem to free any memory allocated by AllocCoTaskMem, ReAllocCoTaskMem, or any equivalent unmanaged method. If the ptr parameter is null, the method does nothing.
FreeCoTaskMem exposes the COM CoTaskMemFree function, which frees all bytes so that you can no longer use the memory that the ptr parameter points to.
In addition to FreeCoTaskMem, the Marshal class provides two other memory-deallocation methods: DestroyStructure and FreeHGlobal.
