glstencilmask(3)
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.
