I want to open a file in R/W mode and be sure that it is empty. Here's how I do this now: Fdelete(name); (1) handle = Fcreate(name,0); (2) Fclose(handle); (3) handle = Fopen(name,2); (4) It is remarkably slow. Is there a better way to do it? If I leave out line 3&4, how does the Atari know I need R/W mode? If I leave out line 1, won't there be two copies of the file? If I leave out line 3, wouldn't I get two different file-descriptors? Please reply by e-mail to jeroen@cs.ruu.nl Thanks in advance! -- Jeroen Fokker, University of Utrecht, the Netherlands
