Like with the previous commit, this replaces instances of:
if (something_bad) {
fprintf (stderr, "%s: error message\n", guestfs_int_program_name);
exit (EXIT_FAILURE);
}
with:
if (something_bad)
error (EXIT_FAILURE, 0, "error message");
(except in a few cases were errno was incorrectly being ignored, in
which case I have fixed that).
It's slightly more complex than the previous commit because we must be
careful to:
- Remove the program name (since error(3) prints it).
- Remove any trailing \n character from the message.
Candidates for replacement were found using:
pcregrep --buffer-size 10M -M '\bfprintf\b.*\n.*\bexit\b' `git ls-files`
