NAME
cgGLSetParameterArray - set the values of an array parameter
SYNOPSIS
#include <Cg/cgGL.h> /* TYPE is float or double */ void cgGLSetParameterArray{1234}{fd}( CGparameter param, long offset, long nelements, const TYPE * v );PARAMETERS
- param
The array parameter that will be set.
- offset
An offset into the array parameter at which to start setting elements. A value of 0 will begin at the first element of the array.
- nelements
The number of elements to set. A value of 0 will default to the total number of elements in the array minus the value of offset.
- v
The array of values used to set the parameter. This must be a contiguous set of values that total nelements times the vector size indicated by the number in the function name.
RETURN VALUES
None.
DESCRIPTION
The cgGLSetParameterArray functions set the value of a scalar or vector array parameter.
Either 1, 2, 3, or 4 values per array element will be set, depending on which function is used.
There are versions of the function that take either float or double values signified by f or d in the function name.

ERRORS
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.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.
HISTORY
The cgGLSetParameterArray functions were introduced in Cg 1.1.
