GLSTENCILMASK(3G) GLSTENCILMASK(3G)

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

void glStencilMask( GLuint mask )












  

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










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.








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