GLSTENCILMASK(3G)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 sten-
cil 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

I'm writing both 8-bit and wide 16-bit data to the screen and an output file. I have no problems with writing out to the screen - for example:
cout<<8-bit data;
wcout<<16-bit data;
Similarly, I have used ofstream for 8-bit and wofstream for 16-bit, for example:
ofstream out;
wofstream wout;... (1 Reply)
Folks,
I am hoping someone out there can help me. I have been writing code for in-excess of 10 years. Throughout all this time I have used Xemacs. I have picked up bits of customizations here and there over the years, but would not profess to be anything of an expert in Lisp (or have a heavily... (3 Replies)

Just wondering how these are accumulated, I recently made a search and noticed that mine had gone up- I'm guessing that it's based on user activity i.e. writing posts but is there a list of actions that accumulate them? (3 Replies)
