Synopsis
#include <Cg/cg.h> CGannotation cgGetNamedTechniqueAnnotation( CGtechnique tech, const char * name );Parameters

The names of a technique's annotations can be discovered by iterating through the annotations (see cgGetFirstTechniqueAnnotation and cgGetNextAnnotation), calling cgGetAnnotationName for each one in turn.
Examples
/* fetch annotation "Apple" from CGtechnique technique */ CGannotation ann = cgGetNamedTechniqueAnnotation( technique, "Apple" );Errors
CG_INVALID_TECHNIQUE_HANDLE_ERROR is generated if tech is not a valid technique.
History
cgGetNamedTechniqueAnnotation was introduced in Cg 1.4.
