Brian,
I thought that Dave was responding to Sreenivas' comments more than he was
responding to anyone else's. Sreenivas' comments make it sound like
StdIOPalm.h eliminates all your problems by defining sprintf as StrPrintF.
As nearly everyone else has pointed out, they are not exactly the same, but
StrPrintF is what the Palm OS provides, so use it if it can do what you
need. It makes no sense whatsoever to include StdIOPalm.h just so you can
hide the fact that you are actually calling StrPrintF when you invoke
sprintf. In fact, all that does is increase the likelihood of programming
errors.
