Specifies the clear value for the stencil buffer.
OpenGL C bindings library: libGL.a
void glClearStencil(GLint Stencil)
| Stencil | Specifies the index used when the stencil buffer is cleared. The default value is 0 (zero). |
The glClearStencil subroutine specifies the index used by glClear to clear the stencil buffer. The Stencil parameter is masked with 2m - 1, where m is the number of bits in the stencil buffer.
| GL_INVALID_OPERATION | Indicates that glClearStencil is called between a call to glBegin and the corresponding call to glEnd. |
Associated gets for the glClearStencil subroutine are as follows. (See the glGet subroutine for more information.)
glGet with argument GL_STENCIL_CLEAR_VALUE
glGet with argument GL_STENCIL_BITS.
| /usr/include/GL/gl.h | Contains C language constants, variable type definitions, and ANSI function prototypes for OpenGL. |
The glBegin or glEnd subroutine, glClear subroutine.
