NAME
cgGetNextLeafParameter - get the next leaf parameter in a program or effect
SYNOPSIS
#include <Cg/cg.h> CGparameter cgGetNextLeafParameter( CGparameter param );PARAMETERS
- param
The current leaf parameter.
RETURN VALUES
cgGetNextLeafParameter returns a the next leaf CGparameter object. NULL is returned if param is invalid or if the program or effect that iteration started from does not have any more leaf parameters.
DESCRIPTION
cgGetNextLeafParameter returns the next leaf parameter (not struct or array parameters) following a given leaf parameter.
EXAMPLES
The following is an example of how to iterate through all the leaf parameters in a program:
CGparameter leaf = cgGetFirstLeafParameter( program ); while(leaf) { /* Do stuff with leaf */ leaf = cgGetNextLeafParameter( leaf ); }In a similar manner, the leaf parameters in an effect can be iterated over starting with a call to cgGetFirstLeafEffectParameter.
ERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if param does not refer to a valid parameter.
HISTORY
cgGetNextLeafParameter was introduced in Cg 1.1.
