[comp.sys.mac.hypercard] Some help with XFCN routines

dragon@hubcap.clemson.edu (Michael E. Quattlebaum) (01/16/90)

I am relatively new to programming XFCNs, so please bear with
me if this is a stupid question.  I am trying to use THINK C's
NumToStr function, but having some trouble.  I thought I could
simply pass it a long int and a str and have it convert the int
to a str (i.e., NumToStr(longint,mystr)).  This did not work.
After looking around some, I discovered that the function also
takes a pointer to the Xcmd Parameter Block (? Not sure about
this part ?), so I tried NumToStr(paramPtr,longint,mystr).  Both
of these gave me a message (something like) the call does not
conform to the prototype for this function.  Am I missing something?
Also, is there a list somewhere that shows me each function that
is unique to the XFCN libraries and what to pass them (types, etc.).
Thanks in advance,
