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.
