cgGetNextLeafParameter(3)

NAME
cgGetNextLeafParameter - get the next leaf parameter in a program or effect

SYNOPSIS
  #include <Cg/cg.h>
  CGparameter cgGetNextLeafParameter( CGparameter param );

PARAMETERS
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 cgGetFirstLeafEffectParameter.

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.
