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

Returns the next leaf CGparameter object.

Returns NULL if param is invalid or if the program or effect from which the iteration started does not have any more leaf parameters.

DESCRIPTION

cgGetNextLeafParameter returns the next leaf parameter (not struct or array parameters) following a given leaf parameter.

In a similar manner, the leaf parameters in an effect can be iterated over starting with a call to the cgGetFirstLeafEffectParameter manpage.

EXAMPLES


  CGparameter leaf = cgGetFirstLeafParameter( program );

  while(leaf)

   {

     /* Do stuff with leaf */

     leaf = cgGetNextLeafParameter( leaf );

   }

ERRORS

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

HISTORY

cgGetNextLeafParameter was introduced in Cg 1.1.
