# glPopDebugGroup

## Name

glPopDebugGroup — pop the active debug group

## C Specification

`void glPopDebugGroup(` | void`)`;

## Description

`glPopDebugGroup` pops the active debug group. After popping a debug group, the GL will also generate a debug output message describing its cause based on the `message` string, the source `source`, and an ID `id` submitted to the corresponding glPushDebugGroup command. `GL_DEBUG_TYPE_PUSH_GROUP` and `GL_DEBUG_TYPE_POP_GROUP` share a single namespace for message `id`. `severity` has the value `GL_DEBUG_SEVERITY_NOTIFICATION`. The `type` has the value `GL_DEBUG_TYPE_POP_GROUP`. Popping a debug group restores the debug output volume control of the parent debug group.

## Errors

`GL_STACK_UNDERFLOW` is generated if an attempt is made to pop the default debug group from the stack.

## Associated Gets

glGet with argument `GL_MAX_DEBUG_MESSAGE_LENGTH`.
