This situation is made-to-order for one of my stdio extensions:

	FILE *fopenstr(str,len,mode)
	char *str;
	int len;
	char *mode;

which produces a stdio stream which reads from or writes into
(according as mode is "r" or "w") the given string.  For BSD systems at
least, this is easy (I believe someone already posted pretty much what
is necessary).  I don't know how easy it would be on a USG system.

There's also fopenfxn(), which makes stdio call a specified function
whenever it wants a character - with this you can build anything you
want.
