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
