2013 Khronos Group glDebugMessageInsert 3G glDebugMessageInsert inject an application-supplied message into the debug message queue void glDebugMessageInsert GLenum source GLenum type GLuint id GLenum severity GLsizei length const char *message 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. 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. 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. 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. glDebugMessageControl, glDebugMessageCallback, glGetDebugMessageLog.
