 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.
