GLGETDEBUGMESSAGELOG(3G)					   OpenGL Manual					  GLGETDEBUGMESSAGELOG(3G)

NAME

       glGetDebugMessageLog - retrieve messages from the debug message log

C SPECIFICATION

       GLuint glGetDebugMessageLog(GLuint count, GLsizei bufSize, GLenum *sources, Glenum *types, GLuint *ids, GLenum *severities,
				   GLsizei *lengths, GLchar *messageLog);

PARAMETERS

       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.

DESCRIPTION

       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.

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.

ERRORS

       GL_INVALID_VALUE is generated if count or bufSize is negative.

NAME

       glGetProgramBinary - return a binary representation of a program object's compiled and linked executable source

C SPECIFICATION

       void glGetProgramBinary(GLuint program, GLsizei bufsize, GLsizei *length, GLenum *binaryFormat, void *binary);

PARAMETERS

       program
	   Specifies the name of a program object whose binary representation to retrieve.

       bufSize
	   Specifies the size of the buffer whose address is given by binary.

       length
	   Specifies the address of a variable to receive the number of bytes written into binary.

       binaryFormat
	   Specifies the address of a variable to receive a token indicating the format of the binary data returned by the GL.

       binary
	   Specifies the address an array into which the GL will return program's binary representation.

DESCRIPTION

       glGetProgramBinary returns a binary representation of the compiled and linked executable for program into the array of bytes whose address
       is specified in binary. The maximum number of bytes that may be written into binary is specified by bufSize. If the program binary is
       greater in size than bufSize bytes, then an error is generated, otherwise the actual number of bytes written into binary is returned in the
       variable whose address is given by length. If length is NULL, then no length is returned.

       The format of the program binary written into binary is returned in the variable whose address is given by binaryFormat, and may be
       implementation dependent. The binary produced by the GL may subsequently be returned to the GL by calling glProgramBinary(), with
       binaryFormat and length set to the values returned by glGetProgramBinary, and passing the returned binary data in the binary parameter.

ERRORS

       GL_INVALID_OPERATION is generated if bufSize is less than the size of GL_PROGRAM_BINARY_LENGTH for program.

       GL_INVALID_OPERATION is generated if GL_LINK_STATUS for the program object is false.

ASSOCIATED GETS

       glGetProgram() with argument GL_PROGRAM_BINARY_LENGTH
