1) Fix usage()
2) Group local variables
3) Idiomatic argv-loop
4) BUGFIX: When the m-flag is specified, POSIX clearly says:
"Set the file permission bits of the newly-created FIFO to the specified mode
value."
This means, that if mkfifo() fails for some reason, it should not try to
chmod() the given path (which has been fixed with the "else if")
A simple testcase is:
$ touch testfile; mkfifo -m 000 testfile;
GNU mkfifo(1): ls -l testfile
-rw-r--r-- 1 testfile
sbase mkfifo(1): ls -l testfile
---------- 1 testfile
5) Add blank line before return
and mark it as finished in the README.
Previously, it would only parse octal mode strings. Given
we have the parsemode()-function in util.h anyway, why not
also use it?
