## Name

glDebugMessageInsert — inject an application-supplied message into the debug message queue

## C Specification

`void glDebugMessageInsert(` | GLenum source,
| GLenum type,
| GLuint id,
| GLenum severity,
| GLsizei length,
| const char *message`)`;

## Parameters

`source`

  The source of the debug message to insert.

`type`

  The type of the debug message insert.

`id`

  The user-supplied identifier of the message to insert.

`severity`

  The severity of the debug messages to insert.

`length`

  The length string contained in the character array whose address is given by `message`.

`message`

  The address of a character array containing the message to insert.

## Description

`glDebugMessageInsert` inserts a user-supplied message into the debug output queue. `source` specifies the source that will be used to classify the message and must be `GL_DEBUG_SOURCE_APPLICATION` or `GL_DEBUG_SOURCE_THIRD_PARTY`. All other sources are reserved for use by the GL implementation. `type` indicates the type of the message to be inserted and may be one of `GL_DEBUG_TYPE_ERROR`, `GL_DEBUG_TYPE_DEPRECATED_BEHAVIOR`, `GL_DEBUG_TYPE_UNDEFINED_BEHAVIOR`, `GL_DEBUG_TYPE_PORTABILITY`, `GL_DEBUG_TYPE_PERFORMANCE`, `GL_DEBUG_TYPE_MARKER`, `GL_DEBUG_TYPE_PUSH_GROUP`, `GL_DEBUG_TYPE_POP_GROUP`, or `GL_DEBUG_TYPE_OTHER`. `severity` indicates the severity of the message and may be `GL_DEBUG_SEVERITY_LOW`, `GL_DEBUG_SEVERITY_MEDIUM`, `GL_DEBUG_SEVERITY_HIGH` or `GL_DEBUG_SEVERITY_NOTIFICATION`. `id` is available for application defined use and may be any value. This value will be recorded and used to identify the message.

`length` contains a count of the characters in the character array whose address is given in `message`. If `length` is negative then `message` is treated as a null-terminated string. The length of the message, whether specified explicitly or implicitly, must be less than or equal to the implementation defined constant `GL_MAX_DEBUG_MESSAGE_LENGTH`.

## Notes

`GL_DEBUG_TYPE_MARKER`, `GL_DEBUG_TYPE_PUSH_GROUP`, `GL_DEBUG_TYPE_POP_GROUP`, and `GL_DEBUG_SEVERITY_NOTIFICATION` are available only if the GL version is 4.3 or higher.

## Errors

`GL_INVALID_ENUM` is generated if any of `source`, `type` or `severity` is not one of the accepted interface types.

`GL_INVALID_VALUE` is generated if the length of the message is greater than the value of `GL_MAX_DEBUG_MESSAGE_LENGTH`.
