glDebugMessageInsert

glDebugMessageInsert: man4/glDebugMessageInsert.xml

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.
