cgGetNextTechnique

> # 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.
