GLGETPROGRAMBINARY(3G)		 OpenGL Manual		GLGETPROGRAMBINARY(3G)

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
