static struct gl_query_object* _mesa_new_query_object	(	GLcontext *	ctx,
		GLuint	id
	)			[static, read]

Allocate a new query object.

This is a fallback routine called via ctx->Driver.NewQueryObject().

Parameters:

	ctx	- rendering context
	id	- the new object's ID

Returns:

pointer to new query_object object or NULL if out of memory.

Software driver fallback. Called via ctx->Driver.WaitQuery().

static void delete_queryobj_cb	(	GLuint	id,
		void *	data,
		void *	userData
	)			[static]

Callback for deleting a query object.

Called by _mesa_HashDeleteAll().
