C SPECIFICATION

11       void glStencilMask( GLuint mask )

PARAMETERS

15       mask  Specifies a bit mask to enable and disable writing of  individual
16             bits in the stencil planes.  Initially, the mask is all 1's.
17

DESCRIPTION

19       glStencilMask  controls  the  writing of individual bits in the stencil
20       planes.  The least significant n bits of mask, where n is the number of
21       bits  in  the stencil buffer, specify a mask.  Where a 1 appears in the
22       mask, it's possible to write to the corresponding bit  in  the  stencil
23       buffer.   Where  a 0 appears, the corresponding bit is write-protected.
24       Initially, all bits are enabled for writing.
25

ERRORS

27       GL_INVALID_OPERATION is generated if glStencilMask is executed  between
28       the execution of glBegin and the corresponding execution of glEnd.
