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`
This is the third rewrite of the virt-df program. It very much
follows the outline of the Perl program which this replaced in
libguestfs 1.7.14.
main.c - main program
domains.c - dealing with libvirt, only used if libvirt is around
at compile time
df.c - getting the stats from libguestfs
output.c - writing the output, CSV output
virt-df.h - header file
Note this also uses the shared options parsing code in
'fish/options.[ch]'.
