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

C Specification

void glSampleMaski( GLuint maskNumber,
  GLbitfield mask);



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


Specifies the new value of the mask sub-word.


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.


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