fglGenTexturesEXT(3G) OpenGL Reference fglGenTexturesEXT(3G)NAMEfglGenTexturesEXT - generate texture names
FORTRAN SPECIFICATION
SUBROUTINE fglGenTexturesEXT( INTEGER*4 n,
CHARACTER*8 textures )
PARAMETERS
n The number of texture names to be generated.
textures An array in which the generated texture names are stored.
DESCRIPTIONfglGenTexturesEXT 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 fglGenTexturesEXT.
The generated textures have no dimensionality; they assume the
dimensionality of the texture target to which they are first bound (see
fglBindTextureEXT).
Texture names returned by a call to fglGenTexturesEXT will not be
returned by subsequent calls, unless they are first deleted with
fglDeleteTexturesEXT.
fglGenTexturesEXT is not included in display lists.
NOTESfglGenTexturesEXT is part of the EXT_texture_object extension. See
fglIntro for more information about using extensions.
ERRORS
GL_INVALID_VALUE is generated if n is negative.
GL_INVALID_OPERATION is generated if fglGenTexturesEXT is executed
between the execution of fglBegin and the corresponding execution of
fglEnd.
ASSOCIATED GETS
fglIsTextureEXT
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.
