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. SEE ALSO
