cgGetNamedEffectAnnotation

NAME

cgGetNamedEffectAnnotation - get an effect annotation by name

SYNOPSIS

  #include <Cg/cg.h>

  CGannotation cgGetNamedEffectAnnotation( CGeffect effect,

                                           const char * name );

PARAMETERS

effect

The effect from which to retrieve the annotation.

name

The name of the annotation to retrieve.

RETURN VALUES

Returns NULL if the effect has no annotation corresponding to name.

DESCRIPTION

The annotations associated with an effect can be retrieved directly by name using cgGetNamedEffectAnnotation. The names of a effect's annotations can be discovered by iterating through the annotations (see cgGetFirstEffectAnnotation and cgGetNextAnnotation), calling cgGetAnnotationName for each one in turn.

EXAMPLES

  /* fetch annotation "Apple" from CGeffect effect */

  CGannotation ann = cgGetNamedEffectAnnotation( effect, "Apple" );

ERRORS

CG_INVALID_EFFECT_HANDLE_ERROR is generated if effect is not a valid effect.

CG_INVALID_POINTER_ERROR is generated if name is NULL.

HISTORY

cgGetNamedEffectAnnotation was introduced in Cg 1.5.
