NAME
cgGLGetMatrixParameterArray - get the values from an matrix array parameterSYNOPSIS
#include <Cg/cgGL.h>
/* TYPE is float or double */
void cgGLGetMatrixParameterArray{fd}{rc}( CGparameter param, long offset, long nelements, TYPE * v );
PARAMETERS
- param
- The matrix 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
- The array into which to retrieve the values. The size of the array must be nelements times the number of elements in the matrix.
RETURN VALUES
None.DESCRIPTION
The cgGLGetMatrixParameterArray functions retrieve an array of values from a matrix array parameter.There are versions of the function that return either float or double values signified by f or d in the function name.
There are versions of the function that assume the array of values is laid out in either row or column order signified by r or c respectively in the function name.
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_NOT_MATRIX_PARAM_ERROR is generated if the elements of param are not matrix parameters.
CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if the offset or the nelements parameter is out of the array bounds.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
HISTORY
The cgGLGetMatrixParameterArray functions were introduced in Cg 1.1.SEE ALSO
