Name

cgGetNextTechnique - iterate through techniques in a effect

Synopsis

#include <Cg/cg.h>

CGtechnique cgGetNextTechnique( CGtechnique tech );

Parameters

tech

The current technique.

Return Values

Returns the next technique in the effect's internal sequence of techniques.

Returns NULL when tech is the last technique in the effect.

Description

The techniques within a effect can be iterated over using cgGetNextTechnique.

Note that no specific order of traversal is defined by this mechanism. The only guarantee is that each technique will be visited exactly once.

Examples

CGtechnique tech = cgGetFirstTechnique( effect );
while( tech )
{
  /* do something with tech */
  tech = cgGetNextTechnique( tech );
}

Errors

CG_INVALID_TECHNIQUE_HANDLE_ERROR is generated if tech is not a valid technique.

History

cgGetNextTechnique was introduced in Cg 1.4.
