* Modernization, no functional change intended:Ingo Schwarze2015-11-071-3/+0
| | | | | | Use the POSIX function getline(3) rather than the slightly dangerous BSD function fgetln(3). Remove the related compatibility code.
* Finally use __progname, err(3) and warn(3).Ingo Schwarze2015-10-111-1/+1
| | | | | | | | | | That's more readable and less error-prone than fumbling around with argv[0], fprintf(3), strerror(3), perror(3), and exit(3). It's a bad idea to boycott good interfaces merely because standards committees ignore them. Instead, let's provide compatibility modules for archaic systems (like commercial Solaris) that still don't have them. The compat module has an UCB Copyright (c) 1993...
* Remove clauses 3 and 4 from Christos Zoulas' BSD license.Ingo Schwarze2015-05-201-3/+2
| | | | | This is safe because Christos did that himself in NetBSD in 2008. No code change.
* * remove FreeBSDismsIngo Schwarze2015-05-201-2/+11

* Now that we have man(1) functionality, add a man(1) manual page.Ingo Schwarze2014-08-211-1/+2
| | | | | I'm importing the totally unchanged OpenBSD version such that all changes can easily be tracked in CVS.
* Provide a fallback version of fts(3) for systems lacking it.Ingo Schwarze2014-08-111-1/+2
| | | | | | I chose the OpenBSD version because it apparently contains various bugfixes that never made it into libnbcompat. To reduce size and complexity, i stripped out the features we don't need.
* Audit malloc(3)/calloc(3)/realloc(3) usage.Ingo Schwarze2014-04-231-0/+1
| | | | | | | * Change eight reallocs to reallocarray to be safe from overflows. * Change one malloc to reallocarray to be safe from overflows. * Change one calloc to reallocarray, no zeroing needed. * Change the order of arguments of three callocs (aesthetical).
* add a LICENSE file for clarity and for the convenience of portersIngo Schwarze2014-04-221-0/+43
