Push a named debug group into the command stream.
||-||The source of the debug message.|
||-||The identifier of the message.|
||-||The length of the message to be sent to the debug output stream.|
||-||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
id , the
GL_DEBUG_TYPE_PUSH_GROUP , and
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_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
glGet with argument
