fglGenTextures(3G) OpenGL Reference fglGenTextures(3G)NAMEfglGenTextures - generate texture names
FORTRAN SPECIFICATION
SUBROUTINE fglGenTextures( INTEGER*4 n,
CHARACTER*8 textures )
PARAMETERS
n Specifies the number of texture names to be generated.
textures Specifies an array in which the generated texture names are
stored.
DESCRIPTIONfglGenTextures 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 fglGenTextures.
The generated textures have no dimensionality; they assume the
dimensionality of the texture target to which they are first bound (see
fglBindTexture).
Texture names returned by a call to fglGenTextures are not returned by
subsequent calls, unless they are first deleted with fglDeleteTextures.
NOTESfglGenTextures is available only if the GL version is 1.1 or greater.
ERRORS
GL_INVALID_VALUE is generated if n is negative.
GL_INVALID_OPERATION is generated if fglGenTextures is executed between
the execution of fglBegin and the corresponding execution of fglEnd.
ASSOCIATED GETS
fglIsTexture
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.
