Note that this function cannot correctly handle binary files
(specifically, files containing C<\0> character which is treated
-as end of string). For those you need to use the C<read_file>
+as end of string). For those you need to use the C<download>
function which has a more complex interface.
Because of the message protocol, there is a transfer limit
of somewhere between 2MB and 4MB. To transfer large files you should use
FTP.
+=head2 checksum
+
+ checksum csumtype path
+
+This call computes the MD5, SHAx or CRC checksum of the
+file named C<path>.
+
+The type of checksum to compute is given by the C<csumtype>
+parameter which must have one of the following values:
+
+=over 4
+
+=item C<crc>
+
+Compute the cyclic redundancy check (CRC) specified by POSIX
+for the C<cksum> command.
+
+=item C<md5>
+
+Compute the MD5 hash (using the C<md5sum> program).
+
+=item C<sha1>
+
+Compute the SHA1 hash (using the C<sha1sum> program).
+
+=item C<sha224>
+
+Compute the SHA224 hash (using the C<sha224sum> program).
+
+=item C<sha256>
+
+Compute the SHA256 hash (using the C<sha256sum> program).
+
+=item C<sha384>
+
+Compute the SHA384 hash (using the C<sha384sum> program).
+
+=item C<sha512>
+
+Compute the SHA512 hash (using the C<sha512sum> program).
+
+=back
+
+The checksum is returned as a printable string.
+
=head2 chmod
chmod mode path
C<value> can be NULL.
+=head2 download
+
+ download remotefilename (filename|-)
+
+Download file C<remotefilename> and save it as C<filename>
+on the local machine.
+
+C<filename> can also be a named pipe.
+
+See also C<upload>, C<cat>.
+
+Use C<-> instead of a filename to read/write from stdin/stdout.
+
=head2 exists
exists path
This is always non-NULL. If it wasn't set already, then this will
return the default path.
+=head2 get-state
+
+ get-state
+
+This returns the current state as an opaque integer. This is
+only useful for printing debug and internal error messages.
+
+For more information on states, see L<guestfs(3)>.
+
=head2 get-verbose
get-verbose
This returns the verbose messages flag.
+=head2 is-busy
+
+ is-busy
+
+This returns true iff this handle is busy processing a command
+(in the C<BUSY> state).
+
+For more information on states, see L<guestfs(3)>.
+
+=head2 is-config
+
+ is-config
+
+This returns true iff this handle is being configured
+(in the C<CONFIG> state).
+
+For more information on states, see L<guestfs(3)>.
+
=head2 is-dir
is-dir path
See also C<stat>.
+=head2 is-launching
+
+ is-launching
+
+This returns true iff this handle is launching the subprocess
+(in the C<LAUNCHING> state).
+
+For more information on states, see L<guestfs(3)>.
+
+=head2 is-ready
+
+ is-ready
+
+This returns true iff this handle is ready to accept commands
+(in the C<READY> state).
+
+For more information on states, see L<guestfs(3)>.
+
=head2 kill-subprocess
kill-subprocess
Some internal mounts are not unmounted by this call.
+=head2 upload
+
+ upload (filename|-) remotefilename
+
+Upload local file C<filename> to C<remotefilename> on the
+filesystem.
+
+C<filename> can also be a named pipe.
+
+See also C<download>.
+
+Use C<-> instead of a filename to read/write from stdin/stdout.
