NAME    [Toc]    [Back]

     istexloaded - returns whether the texture with the	passed id is resident
     in	texture	memory

C SPECIFICATION    [Toc]    [Back]

     long istexloaded(long target, long	id)

PARAMETERS    [Toc]    [Back]

     target   expects the texture resource to which the	texture	function
	      definition is to be bound.  There	is one appropriate resource,
	      TX_TEXTURE_0.

     id	      expects the id of	the texture that is being queried.

FUNCTION RETURN	VALUE
     The returned value	for this function is either 0 or 1.

     0	 indicates that	the texture is not resident in texture memory.

     1	 indicates that	the texture is resident	in texture memory.

DESCRIPTION    [Toc]    [Back]

     istexloaded returns a value that indicates	whether	a texture is loaded
     into texture memory. If it	is not,	then the next texbind for that texture
     will require a load which is generally fairly expensive. If it is then
     the texbind will not require a load, and the texbind will be relatively
     inexpensive.
