NAME    [Toc]    [Back]

     glGenTextures - generate texture names

C SPECIFICATION    [Toc]    [Back]

     void glGenTextures( GLsizei n,
			 GLuint	*textures )

PARAMETERS    [Toc]    [Back]

     n	       Specifies the number of texture names to	be generated.

     textures  Specifies an array in which the generated texture names are
	       stored.

DESCRIPTION    [Toc]    [Back]

     glGenTextures 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 glGenTextures.

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

     Texture names returned by a call to glGenTextures are not returned	by
     subsequent	calls, unless they are first deleted with glDeleteTextures.

NOTES    [Toc]    [Back]

     glGenTextures is available	only if	the GL version is 1.1 or greater.

ERRORS    [Toc]    [Back]

     GL_INVALID_VALUE is generated if n	is negative.

     GL_INVALID_OPERATION is generated if glGenTextures	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.
