NAME    [Toc]    [Back]

       glStencilMask  - control the writing of individual bits in
       the stencil planes

SYNOPSIS    [Toc]    [Back]

       void glStencilMask(
               GLuint mask );

PARAMETERS    [Toc]    [Back]

       Specifies a bit mask to  enable  and  disable  writing  of
       individual  bits  in  the  stencil planes.  Initially, the
       mask is all 1's.

DESCRIPTION    [Toc]    [Back]

       glStencilMask() controls the writing of individual bits in
       the  stencil planes. The least significant n bits of mask,
       where n is the number of bits in the stencil buffer, specify
  a  mask. Where a 1 appears in the mask, it's possible
       to write to the corresponding bit in the  stencil  buffer.
       Where  a  0  appears,  the corresponding bit is write-protected.
 Initially, all bits are enabled for writing.

ERRORS    [Toc]    [Back]

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