glPushDebugGroup 3G
glPushDebugGroup push a named debug group into the command stream

## C Specification

void `glPushDebugGroup` GLenum source GLuint id GLsizei length const char * message

## Parameters

source

  The source of the debug message.

id

  The identifier of the message.

length

  The length of the message to be sent to the debug output stream.

message

  The a string containing the message to be sent to the debug output stream.

## Description

`glPushDebugGroup` pushes a debug group described by the string message into the command stream. The value of id specifies the ID of messages generated. The parameter length contains the number of characters in message. If length is negative, it is implied that message contains a null terminated string. The message has the specified source and id, the type `GL_DEBUG_TYPE_PUSH_GROUP`, and severity `GL_DEBUG_SEVERITY_NOTIFICATION`. The GL will put a new debug group on top of the debug group stack which inherits the control of the volume of debug output of the debug group previously residing on the top of the debug group stack. Because debug groups are strictly hierarchical, any additional control of the debug output volume will only apply within the active debug group and the debug groups pushed on top of the active debug group.

## Errors

`GL_INVALID_ENUM` is generated if the value of source is neither `GL_DEBUG_SOURCE_APPLICATION` nor `GL_DEBUG_SOURCE_THIRD_PARTY`.

`GL_INVALID_VALUE` is generated if length is negative and the number of characters in message, excluding the null-terminator, is not less than the value of `GL_MAX_DEBUG_MESSAGE_LENGTH`.

## Associated Gets

glGet with argument `GL_MAX_DEBUG_MESSAGE_LENGTH`.
