Define Documentation

#define cheapPrintf (  val   )

Value: if (val < 10) \ *xpos = '0'; \ else \ *xpos = '0' + (val / 10); \ *(xpos+1) = '0' + (val % 10)

#define UNDEFINED_IN_CRAM

#define SWALLOW_CR (   )

Logging code: if verbosity

#define TIMER_INTERVAL   0.25f

Global Sleep functions that work for windows and mac/unix. Note the use of the global flag gStopNow, which interrupts timers.

---

Function Documentation

string initFileName (   )

read/write the init file (typ. ~/.cslrc) The reader takes a char key, as in string initMsg(CGestalt::initFileText('T')); which looks for a line starting with "T " in the file and returns the part after the "T " The write function takes a key and a string to store.
