count
The number of debug messages to retrieve from the log.
bufSize
The size of the buffer whose address is given by messageLog.
sources
The address of an array of variables to receive the sources of the retrieved messages.
types
The address of an array of variables to receive the types of the retrieved messages.
ids
The address of an array of unsigned integers to receive the ids of the retrieved messages.
severities
The address of an array of variables to receive the severites of the retrieved messages.
lengths
The address of an array of variables to receive the lengths of the received messages.
messageLog
The address of an array of characters that will receive the messages.
glGetDebugMessageLog retrieves messages from the debug message log. A maximum of
count messages are retrieved from the log. If sources
is not NULL then the source of each message is written into up to count elements
of the array. If types
is not NULL then the type of each message is written into up to count elements
of the array. If id
is not NULL then the identifier of each message is written into up to count elements
of the array. If severities
is not NULL then the severity of each message is written into up to count elements
of the array. If lengths
is not NULL then the length of each message is written into up to count elements
of the array.
messageLog specifies the address of a character array into which the debug messages
will be written. Each message will be concatenated onto the array starting at the first element of messageLog.
bufSize specifies the size of the array messageLog. If a message will not
fit into the remaining space in messageLog then the function terminates and returns the number
of messages written so far, which may be zero.
If glGetDebugMessageLog returns zero then no messages are present in the debug log, or there
was not enough space in messageLog to retrieve the first message in the queue. If messageLog
is NULL then no messages are written and the value of bufSize is ignored.
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_INVALID_VALUE is generated if count or bufSize is negative.
