 When the application is linked with a debug version of the C run-time libraries, **_aligned_msize** resolves to [_aligned_msize_dbg](aligned-msize-dbg.md). For more information about how the heap is managed during the debugging process, see [The CRT Debug Heap](/visualstudio/debugger/crt-debug-heap-details).
 
-This function validates its parameter. If *memblock* is a null pointer or *alignment* is not a power of 2, **_msize** invokes an invalid parameter handler, as described in [Parameter Validation](../../c-runtime-library/parameter-validation.md). If the error is handled, the function sets **errno** to **EINVAL** and returns -1.

 By default, this function's global state is scoped to the application. To change this, see [Global state in the CRT](../global-state.md).
