[] When I buffer I/O myself (see the source code for my uu*code, MORE, etc) (oops: those are in AL, not C!) (In C: my version of microEMACS) I first read the file attributes (using Setdta() and Fsfirst()) and isolate the file size. Later, when reading the file in chunks (of 4.5 or 9 or 18K) I keep track of the amount remaining to be read. In the last call to Fread() I only ask for the amount that I know is there! (Why all the trouble? - 'cause this is _much_ faster than using the byte-by-byte UNIX-like fopen(),fread()...) - Moshe Braner
