glPushDebugGroup — push a named debug group into the command stream
void glPushDebugGroup( | GLenum source, |
GLuint id, | |
GLsizei length, | |
const char * message) ; |
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.
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.
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
.
