NAME
cgGLGetParameterArray - get the values from an array parameterSYNOPSIS
#include <Cg/cgGL.h>
/* TYPE is float or double */
void cgGLGetParameterArray{1234}{fd}( CGparameter param, long offset, long nelements, const TYPE * v );
PARAMETERS
- param
- The array parameter from which the values will be retrieved.
- offset
- An offset into the array parameter at which to start getting elements. A value of 0 will begin at the first element of the array.
- nelements
- The number of elements to get. A value of 0 will default to the total number of elements in the array minus the value of offset.
- v
- Destination buffer into which the values will be written. The size of v must be nelements times the vector size indicated by the number in the function name.
RETURN VALUES
None.DESCRIPTION
The cgGLGetParameterArray functions retrieve the values from a scalar or vector array parameter.There are versions of each function that return either float or double values signified by f or d in the function name.
Either 1, 2, 3, or 4 values per array element is returned depending on which function is used.
EXAMPLES
to-be-writtenERRORS
CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.CG_ARRAY_PARAM_ERROR is generated if param is not an array parameter.
CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if offset or nelements is outside the bounds of param.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
HISTORY
The cgGLGetParameterArray functions were introduced in Cg 1.1.SEE ALSO
