cgGetParameterValues(3)

NAME
cgGetParameterValues - get a program parameter's values

SYNOPSIS
  #include <Cg/cg.h>
  const double * cgGetParameterValues( CGparameter param,
                                       CGenum value_type,
                                       int * nvalues );

PARAMETERS
The program parameter. Determines what type of value to return. Valid enumerants are :
    Returns the constant values for parameters that have constant variability. See the cgGetParameterVariability manpage for more information. Returns the default values for a uniform parameter. Returns the current values for a uniform parameter.
Pointer to integer that will be initialized to store the number of values returned.

RETURN VALUES
Returns a pointer to an array of double values. The number of values in the array is returned via the nvalues parameter.

Returns NULL if no values are available, and nvalues will be 0.

DESCRIPTION
cgGetParameterValues allows the application to retrieve default, current, or constant values from uniform parameters.

EXAMPLES

ERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

CG_INVALID_PARAMETER_ERROR is generated if nvalues is NULL.

CG_INVALID_ENUMERANT_ERROR is generated if value_type is not CG_CONSTANT, CG_DEFAULT, or CG_CURRENT.

HISTORY
cgGetParameterValues was introduced in Cg 1.1.
