glsamplemaski

GLSAMPLEMASKI(3G)						    OpenGL 3.3							 GLSAMPLEMASKI(3G)

NAME

       glSampleMaski - set the value of a sub-word of the sample mask

C SPECIFICATION

       void glSampleMaski(GLuint maskNumber, GLbitfield mask);

PARAMETERS

       maskNumber
	   Specifies which 32-bit sub-word of the sample mask to update.

       mask
	   Specifies the new value of the mask sub-word.

DESCRIPTION

       glSampleMaski sets one 32-bit sub-word of the multi-word sample mask, GL_SAMPLE_MASK_VALUE.

       maskIndex specifies which 32-bit sub-word of the sample mask to update, and mask specifies the new value to use for that sub-word.
       maskIndex must be less than the value of GL_MAX_SAMPLE_MASK_WORDS. Bit B of mask word M corresponds to sample 32 x M + B.

NOTES

       glSampleMaski is available only if the GL version is 3.2 or greater, or if the ARB_texture_multisample extension is supported.

ERRORS

       GL_INVALID_VALUE is generated if maskIndex is greater than or equal to the value of GL_MAX_SAMPLE_MASK_WORDS.
