Modified files:
include printf.h
lib/libc/stdio Makefile.inc xprintf.c xprintf_vis.c
Added files:
lib/libc/stdio xprintf_errno.c xprintf_quote.c
Log:
Make the %V{is} extension handle a NULL pointer like %s does: output "(null)"
Add %M{essage} extension which prints an errno value as the
corresponding string if possible or numerically otherwise.
It is not currently possible to do the syslog(3) like %m extension
because errno would need to get capatured on entry to the first
function in the printf family, so %M requires you to supply errno
as an argument.
Add %Q{uote} extension which will print a string in double quotes with
appropriate back-slash escapes (only) if necessary.
