Name

cgGLGetTextureEnum - get the OpenGL enumerant for the texture unit associated with a parameter

Synopsis

#include <Cg/cgGL.h>

GLenum cgGLGetTextureEnum( CGparameter param );

Parameters

param
The texture parameter for which the OpenGL texture unit enumerant will be retrieved.

Return Values

Returns a GLenum of the form GL_TEXTURE#_ARB.

Returns GL_INVALID_OPERATION if an error occurs.

Description

cgGLGetTextureEnum returns the OpenGL enumerant for the texture unit assigned to param. The enumerant has the form GL_TEXTURE#_ARB where # is the texture unit number.

Examples

to-be-written

Errors

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

CG_INVALID_PARAMETER_ERROR is generated if param is not a texture parameter or if the operation fails for any other reason.

History

cgGLGetTextureEnum was introduced in Cg 1.1.
