glGetPolygonStipple - return the polygon stipple pattern

void glGetPolygonStipple( GLubyte *mask )












  

  
Returns the stipple pattern. The initial value is all 1's.










glGetPolygonStipple returns to mask a 32 * 32
    polygon stipple pattern. The pattern is packed into memory as if
    glReadPixels with both height and width of 32,
    type of GL_BITMAP, and format of GL_COLOR_INDEX
    were called, and the stipple pattern were stored in an internal 32 * 32
    color index buffer. Unlike glReadPixels, however, pixel transfer
    operations (shift, offset, pixel map) are not applied to the returned
    stipple image.








If an error is generated, no change is made to the contents of
    mask.








GL_INVALID_OPERATION is generated if
    glGetPolygonStipple is executed between the execution of
    glBegin and the corresponding execution of glEnd.
