I am writing a program in Think C 4.0 that needs to read numeric input from
an ASCII text file.  Under UNIX this is very easy to do with fscanf() and so
on.  Is there a simple way to do this with a Macintosh?  

I would like to be able to use SFGetFile() to allow the user to pick the
file they would like to open, but the SFReply doesn't seem to be very useful
to the ANSI C libraries for Think C.  The Think C documentation says that
scanf() requires a pointer to type FILE, which I am not sure how to get.

I could of course write my own routines to use the Toolbox calls to read
data from the file, and then convert the ASCII character codes to a numeric
data type, but this seems like a lot of work compared to using library
routines to do it for me.

Any help you can give me would be greatly appreciated.
