### Parameters

*pNumMetaCommands*\
Type: UINT \*

A pointer to a [UINT](https://learn.microsoft.com/en-us/windows/desktop/WinProg/windows-data-types) containing the number of meta commands to query for. This field determines the size of the <i>pDescs</i> array, unless <i>pDescs</i> is **nullptr**.

*pDescs*\
Type: D3D12\_META\_COMMAND\_DESC \*

An optional pointer to an array of [D3D12\_META\_COMMAND\_DESC](/reference/graphics/d3d12/structs/d3d12_meta_command_desc_public) containing the descriptions of the available meta commands. Pass `nullptr` to have the number of available meta commands returned in <i>pNumMetaCommands</i>.

### Return value
