DESCRIPTION
If PutCode or SetCode fails, a NULL is returned and SDL_SetError. Otherwise, the start adress of the machine code buffer is returned, which is also the input argument of PutCode and RunCode.
If SDL_SetRowStretchCode fails, the SDL_StretchRow1 function must be used instead. The SDL_StretchRow1 function and its cousins are singular routines that work in a tight loop to scale a single row. The number specifies the byte-width of each pixel (it is not a bit-width!).
