NAME    [Toc]    [Back]

     glGenTexturesEXT -	generate texture names

C SPECIFICATION    [Toc]    [Back]

     void glGenTexturesEXT( GLsizei n,
			    GLuint *textures )

PARAMETERS    [Toc]    [Back]

     n	       The number of texture names to be generated.

     textures  An array	in which the generated texture names are stored.

DESCRIPTION    [Toc]    [Back]

     glGenTexturesEXT returns n	texture	names in textures.  There is no
     guarantee that the	names form a contiguous	set of integers; however, it
     is	guaranteed that	none of	the returned names was in use immediately
     before the	call to	glGenTexturesEXT.

     The generated textures have no dimensionality; they assume	the
     dimensionality of the texture target to which they	are first bound	(see
     glBindTextureEXT).

     Texture names returned by a call to glGenTexturesEXT will not be returned
     by	subsequent calls, unless they are first	deleted	with
     glDeleteTexturesEXT.

     glGenTexturesEXT is not included in display lists.

NOTES    [Toc]    [Back]

     glGenTexturesEXT is part of the EXT_texture_object	extension.  See
     glIntro for more information about	using extensions.

ERRORS    [Toc]    [Back]

     GL_INVALID_VALUE is generated if n	is negative.

     GL_INVALID_OPERATION is generated if glGenTexturesEXT is executed between
     the execution of glBegin and the corresponding execution of glEnd.

MACHINE	DEPENDENCIES
     RealityEngine, RealityEngine2, and	VTX systems do not support texture
     name sharing.  Texture names are always local to the rendering context
     which was active at the time the names were created.

     The implementation	on O2 systems uses a minimum of	64K bytes for every
     texture object defined.
