NAME
glStencilMask
- control the writing of individual bits in the stencil planes
C SPECIFICATION
void ggllSStteenncciillMMaasskk(
GLuint _m_a_s_k )
delim $$
PARAMETERS
-
_m_a_s_k
-
Specifies a bit mask to enable and disable writing of individual bits
in the stencil planes.
Initially, the mask is all 1's.
DESCRIPTION
ggllSStteenncciillMMaasskk controls the writing of individual bits in the stencil planes.
The least significant $n$ bits of _m_a_s_k,
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
GGLL__IINNVVAALLIIDD__OOPPEERRAATTIIOONN is generated if ggllSStteenncciillMMaasskk
is executed between the execution of ggllBBeeggiinn
and the corresponding execution of ggllEEnndd.
