Hello everyone, I am currently writing a C program on Unix machines. What I want to do is to store the file names in a directory into a character array. So I can do something to those files. I want to use Unix system calls to handle it. Could anyone help me out with that? Thanks in advance. --Jim hev7@ub.cc.umich.edu

Could anyone help me out with that? I think opendir(), readdir() etc. can handle this problems. Check your man pages. -ping

Which machines understand terminfo, termcap, or curses, but do not also understand an environment varible like TERMINFO, TERMCAP or TERMCAPS for individual second guessing of administrators? I ask only extend my list of broken, compeating machines. Since at least 4.2BSD and maybe 4.1c, that family has had TERMCAP (or was it TERMCAPS?), so the solar and Boston crowd are ok. SVR3 knows about TERMINFO, so most PC's and many SV machines are ok. Did SVR0 have TERMCAP? Vernon Schryver vjs@sgi.com

There are some portability pitfalls so the routine to fetch the file names should be encapsulated. The major variants that I can think of offhand are: (a) BSD Uses <sys/dir.h> (b) SYS V Uses <dirent.h> (c) SYS V Older versions of SYS V may not have these routines. You can write your own. THe directory is a file containing an array of structures which can be read. The format is in the manual. (d) VMS Write your own. There are C callable VMS library routines for extracting the needed information. (e) Primos Has a routine called lsdir which returns just what you want. -- Richard Harter, Software Maintenance and Development Systems, Inc.
