glIsTexture(3G)

NAME
     glIsTexture - determine if a name corresponds to a texture


C SPECIFICATION
     GLboolean glIsTexture( GLuint texture )


PARAMETERS
     texture  Specifies a value that may be the name of a texture.

DESCRIPTION
     glIsTexture returns GL_TRUE if texture is currently the name of a
     texture.  If texture is zero, or is a non-zero value that is not
     currently the name of a texture, or if an error occurs, glIsTexture
     returns GL_FALSE.

NOTES
     glIsTexture is available only if the GL version is 1.1 or greater.

ERRORS
     GL_INVALID_OPERATION is generated if glIsTexture 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.
