GLGETPOLYGONSTIPPLE(3G)		 OpenGL Manual	       GLGETPOLYGONSTIPPLE(3G)

NAME
       glGetPolygonStipple - return the polygon stipple pattern

C SPECIFICATION
       void glGetPolygonStipple(GLubyte * pattern);

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

DESCRIPTION
       glGetPolygonStipple returns to pattern 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 a non-zero named buffer object is bound to the GL_PIXEL_PACK_BUFFER
       target (see glBindBuffer()) while a polygon stipple pattern is
       requested, pattern is treated as a byte offset into the buffer object's
       data store.

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

ERRORS
       GL_INVALID_OPERATION is generated if a non-zero buffer object name is
       bound to the GL_PIXEL_PACK_BUFFER target and the buffer object's data
       store is currently mapped.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is
       bound to the GL_PIXEL_PACK_BUFFER target and the data would be packed
       to the buffer object such that the memory writes required would exceed
       the data store size.

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

ASSOCIATED GETS
       glGet() with argument GL_PIXEL_PACK_BUFFER_BINDING
