NAME
cgGLSetParameterPointer - sets a varying parameter with an attribute array
SYNOPSIS
#include <Cg/cgGL.h> void cgGLSetParameterPointer( CGparameter param, GLint fsize, GLenum type, GLsizei stride, const GLvoid * pointer );PARAMETERS
- param
The parameter that will be set.
- fsize
The number of coordinates per vertex.
- type
The data type of each coordinate. Possible values are GL_UNSIGNED_BYTE, GL_SHORT, GL_INT, GL_FLOAT, and GL_DOUBLE.
- stride
The byte offset between consecutive vertices. When stride is 0 the array is assumed to be tightly packed.
- pointer
The pointer to the first coordinate in the vertex array.
RETURN VALUES
None.
DESCRIPTION
cgGLSetParameterPointer sets a varying parameter to a given vertex array in the typical OpenGL style. See the OpenGL documentation on the various vertex array functions (e.g. glVertexPointer, glNormalPointer, etc...) for more information.

ERRORS
CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.
CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
CG_UNSUPPORTED_GL_EXTENSION_ERROR is generated if param required an OpenGL extension that is not available.
CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.
HISTORY
cgGLSetParameterPointer was introduced in Cg 1.1.
