printf: Allow multibyte characters for ' form, avoid negative codes.

2011-05-28T11:37:47Z

Examples: LC_ALL=en_US.UTF-8 printf '%d\n' $(printf \'\\303\\244) LC_ALL=en_US.ISO8859-1 printf '%d\n' $(printf \'\\344) Both of these should print 228. Like some other shells, incomplete or invalid multibyte characters yield the value of the first byte without a warning. Note that there is no general way to go back from the character code to the character.

printf: Note that this is used both as a normal program and a shell builtin.

printf: Do not use sh memory functions in sh builtin.

These functions throw exceptions if they fail, possibly causing memory leaks. The normal out-of-memory handling suffices. The INTOFF around almost all of printf prevents memory leaks due to SIGINT.

sh: Make warnings in the printf builtin non-fatal, like in the program.

The #define for warnx now behaves much like the libc function (except that it uses sh command name and output). Also, it now uses C99 __VA_ARGS__ so there is no need for three different macros for 0, 1 or 2 parameters.

Revert r216423 per request from Jilles.

The new behavior prevents us from being able to bail out explicitly on unknown options that we have not implemented. BASH for instance have introduced a '-v' for printf(1) builtin and it seems to be bad to pretend that we supported it and have a script break silently.

When printf is being used as a sh(1) builtin, it can not call

exit(3) as pointed out by jilles@ so revert to using return(), also change the return value back to 1 as requested by bde@. This is logically a revert of revision 216422.

We work on ctype's and not only on numbers so set LC_ALL instead of

IEEE Std 1003.1-2008, Section 1.4, Utility Description Defaults says

2010-12-14T01:16:56Z

that when the options section is listed as "None", utility shall recognize "--" as a first argument to be discarded. This implementation is largely based on OpenBSD implementation but we do slightly differently: a) We skip argv[0] as the first step; b) We test whether the next argument is "--" and ignore it. With this change one will get: %printf usage: printf format [arguments ...] %printf -v -v%printf -- -v -v% %printf -- usage: printf format [arguments ...] Which matches the behavior observed on a Debian system but different from the Illumos change.

Make use of EX_USAGE for usage().
