- determine if a name corresponds to a texture



C SPECIFICATION


PARAMETERS

       _param1  Specifies  a value that may be the name of a tex-
                ture.


DESCRIPTION

       glIsTexture returns GL_TRUE if _param1  is  currently  the
       name  of  a texture.  If _param1 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  exe-
       cuted between the execution of glBegin and the correspond-
       ing execution of glEnd.
