Name

cgD3D10GetOptimalOptions - get the best set of compiler options for a profile

Synopsis

#include <Cg/cgD3D10.h>

char const ** cgD3D10GetOptimalOptions( CGprofile profile );

Parameters

profile

The profile whose optimal arguments are requested.

Return Values

Returns a null-terminated array of strings representing the optimal set of compiler options for profile.

Returns NULL if no D3D device is currently set.

Description

cgD3D10GetOptimalOptions returns the best set of compiler options for a given profile. This is an expanded interface function because it needs to know about the D3D device to determine the most optimal options.

The elements of the returned array are meant to be used as part of the args parameter to cgCreateProgram or cgCreateProgramFromFile.

The returned string does not need to be destroyed by the application. However, the contents could change if the function is called again for the same profile but a different D3D device.

Examples

const char* vertOptions[]  = { myCustomArgs,
                               cgD3D10GetOptimalOptions(vertProfile),
                               NULL };

// create the vertex shader
CGprogram myVS = cgCreateProgramFromFile( context,
                                          CG_SOURCE,
                                          "vshader.cg",
                                          vertProfile,
                                          "VertexShader",
                                          vertOptions);

Errors

None.
