GLSTENCILMASK(3G)

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

C SPECIFICATION
void glStencilMask( GLuint mask )

PARAMETERS

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

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

ASSOCIATED GETS
glGet with argument GL_STENCIL_WRITEMASK
glGet with argument GL_STENCIL_BITS
