## Name

glBlendBarrier — specifies a boundary between advanced blending passes

## C Specification

`void glBlendBarrier(` | void`)`;

## Description

`glBlendBarrier` specifies a boundary between passes when using advanced blend equations. Any command that causes the value of a sample to be modified using the framebuffer is considered to touch the sample, including clears, blended or unblended primitives, and BlitFramebuffer copies. Defined results are guaranteed only if each sample is touched no more than once in any single rendering pass.
