	)

Find the max index in the given element/index buffer.

GLboolean _mesa_validate_DrawArrays	(	GLcontext *	ctx,
		GLenum	mode,
		GLint	start,
		GLsizei	count
	)

Called from the tnl module to error check the function parameters and verify that we really can draw something.

Returns:

GL_TRUE if OK to render, GL_FALSE if error found

		GLint	basevertex
	)

Error checking for glDrawElements().

Includes parameter checking and VBO bounds checking.

Returns:

GL_TRUE if OK to render, GL_FALSE if error found
