cgValidateTechnique

> # NAME

> cgValidateTechnique - validate a technique from an effect

> # SYNOPSIS

>       #include <Cg/cg.h>

>       CGbool cgValidateTechnique( CGtechnique tech );

> # PARAMETERS

> tech

>   The technique handle to validate.

> # RETURN VALUES

> Returns CG_TRUE if all of the state assignments in all of the passes in tech are valid and can be used on the current hardware.

> Returns CG_FALSE if any state assignment fails validation, or if an error occurs.

> # DESCRIPTION

> cgValidateTechnique iterates over all of the passes of a technique and tests to see if every state assignment in the pass passes validation.

> # EXAMPLES

>       CGcontext context = cgCreateContext();
>       CGeffect effect = cgCreateEffectFromFile(context, filename, NULL);

>       CGtechnique tech = cgGetFirstTechnique(effect);
>       while (tech && cgValidateTechnique(tech) == CG_FALSE) {
>         fprintf(stderr, "Technique %s did not validate.  Skipping.\n",
>           cgGetTechniqueName(tech));
>         tech = cgGetNextTechnique(tech);
>       }

>       if (tech) {
>         fprintf(stderr, "Using technique %s.\n", cgGetTechniqueName(tech));
>       } else {
>         fprintf(stderr, "No valid technique found\n");
>         exit(1);
>       }

> # ERRORS

> CG_INVALID_TECHNIQUE_HANDLE_ERROR is generated if tech is not a valid technique.

> # HISTORY

> cgValidateTechnique was introduced in Cg 1.4.
