NAME
glDebugMessageControl - control the reporting of debug messages in a debug context
C SPECIFICATION
void glDebugMessageControl(GLenum source, GLenum type, GLenum severity, GLsizei count, const GLuint *ids,
GLboolean enabled);
PARAMETERS
source
The source of debug messages to enable or disable.
type
The type of debug messages to enable or disable.
severity
The severity of debug messages to enable or disable.
count
The length of the array ids.
ids
The address of an array of unsigned integers contianing the ids of the messages to enable or disable.
enabled
A Boolean flag determining whether the selected messages should be enabled or disabled.
DESCRIPTION
glDebugMessageControl controls the reporting of debug messages generated by a debug context. The
parameters source, type and severity form a filter to select messages from the pool of potential messages
generated by the GL.
source may be GL_DEBUG_SOURCE_API, GL_DEBUG_SOURCE_WINDOW_SYSTEM_, GL_DEBUG_SOURCE_SHADER_COMPILER,
GL_DEBUG_SOURCE_THIRD_PARTY, GL_DEBUG_SOURCE_APPLICATION, GL_DEBUG_SOURCE_OTHER to select messages
generated by usage of the GL API, the window system, the shader compiler, third party tools or libraries,
explicitly by the application or by some other source, respectively. It may also take the value
GL_DONT_CARE. If source is not GL_DONT_CARE then only messages whose source matches source will be
referenced.
type 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 to
indicate the type of messages describing GL errors, attempted use of deprecated features, triggering of
undefined behavior, portability issues, performance notifications, markers, group push and pop events,
and other types of messages, respectively. It may also take the value GL_DONT_CARE. If type is not
GL_DONT_CARE then only messages whose type matches type will be referenced.
severity may be one of GL_DEBUG_SEVERITY_LOW, GL_DEBUG_SEVERITY_MEDIUM, or GL_DEBUG_SEVERITY_HIGH to
select messages of low, medium or high severity messages or to GL_DEBUG_SEVERITY_NOTIFICATION for
notifications. It may also take the value GL_DONT_CARE. If severity is not GL_DONT_CARE then only
messages whose severity matches severity will be referenced.
ids contains a list of count message identifiers to select specific messages from the pool of available
messages. If count is zero then the value of ids is ignored. Otherwise, only messages appearing in this
list are selected. In this case, source and type may not be GL_DONT_CARE and severity must be
GL_DONT_CARE.
If enabled is GL_TRUE then messages that match the filter formed by source, type, severity and ids are
enabled. Otherwise, those messages are disabled.
NOTES
Although debug messages may be enabled in a non-debug context, the quantity and detail of such messages
may be substantially inferior to those in a debug context. In particular, a valid implementation of the
debug message queue in a non-debug context may produce no messages at all.
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_VALUE is generated if count is negative.
GL_INVALID_ENUM is generated if any of source, type or severity is not one of the accepted interface
types.
GL_INVALID_OPERATION is generated if count is non-zero and either source or type is GL_DONT_CARE or if
severity is not GL_DONT_CARE.
