Macro Definition Documentation

#define DBG

(

...

)

Value:

do {                    \
        __VA_ARGS__;        \
    } while (0)

instead of guarding every debug output with #if SDH_RS232_CYGWIN_DEBUG / #endif we use this DBG macro that expands to a stream output to a dbg object or to ";" depending on the value of SDH_RS232_CYGWIN_DEBUG

Definition at line 79 of file rs232-cygwin.cpp.

#define SDH_RS232_CYGWIN_DEBUG   1

Flag, if true then code for debug messages is included.

The debug messages must still be enabled at run time by setting the some_cRS232_object.dbg.SetFlag(1).

This 2 level scheme is used since this is the lowlevel communication, so debug outputs might really steal some performance.
