Execute a command list over one or more thread groups.
void DispatchIndirect( ID3D11Buffer *pBufferForArgs, UINT AlignedByteOffsetForArgs );
A byte-aligned offset between the start of the buffer and the arguments.
You call the DispatchIndirect method to execute commands in a compute shader.
When an application creates a buffer that is associated with the ID3D11Buffer interface that pBufferForArgs points to, the application must set the D3D11_RESOURCE_MISC_DRAWINDIRECT_ARGS flag in the MiscFlags member of the D3D11_BUFFER_DESC structure that describes the buffer. To create the buffer, the application calls the ID3D11Device::CreateBuffer method and in this call passes a pointer to D3D11_BUFFER_DESC in the pDesc parameter.
