From: utzoo!decvax!goutal Newsgroups: net.lang.c Title: filter i/o in C Article-I.D.: decvax.405 Posted: Wed Jan 26 00:32:05 1983 Received: Fri Jan 28 03:44:40 1983 Most implementations of C that I know of prohibit me from having the same file open for reading and writing at the same time. Most operating systems that I use, however, think this is okay, under various interpretations. The most obvious example of why I might want to do this is a simple filter or, more clearly, an editor of some sort; I want to read from a file and write the result back into the same file (or a new version of it, more likely). Anybody know how I should do this? Just mail to me, I guess. -- Kenn (decvax!)goutal
