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
