43 * indication, ie. 0 or -1.
47 (* "RInt" as a return value means an int which is -1 for error
48 * or any value >= 0 on success. Only use this for smallish

53 (* "RInt64" is the same as RInt, but is guaranteed to be able

55 * (so -1 cannot be a valid, non-error return value).

80 (* "RString" is a returned string. It must NOT be NULL, since
81 * a NULL return indicates an error. The caller frees this.
85 (* "RStringList" is a list of strings. No string in the list
86 * can be NULL. The caller frees the strings and the array.
88 | RStringList of string
90 (* "RStruct" is a function which returns a single named structure
91 * or an error indication (in C, a struct, and in other languages
92 * with varying representations, but usually very efficient). See
93 * after the function list below for the structures.

111 (* "RBufferOut" is handled almost exactly like RString, but
112 * it allows the string to contain arbitrary 8 bit data including
113 * ASCII NUL. In the C API this causes an implicit extra parameter

115 * returns the actual size of the return buffer in bytes.

1386 of these, then the corresponding parameter is omitted. Usually for
1387 'large' disks, you can just pass C<0> for these, but for small

7345 The C<Sys::Guestfs> module provides a Perl XS binding to the
7346 libguestfs API for examining and modifying virtual machine
7349 Amongst the things this is good for: making batch configuration
7350 changes to guests, getting disk used/free statistics (see also:
7351 virt-df), migrating between virtualization systems (see also:
7352 virt-p2v), performing partial backups, performing partial guest
7353 clones, cloning guests and changing registry/UUID/hostname info, and
7356 Libguestfs uses Linux kernel and qemu code, and can access any type of
7357 guest filesystem that Linux and qemu can, including but not limited
7358 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
7359 schemes, qcow, qcow2, vmdk.
7361 Libguestfs provides ways to enumerate guest storage (eg. partitions,
7362 LVs, what filesystem is in each LV, etc.). It can also run commands
7363 in the context of the guest. Also you can access filesystems over FTP.
7365 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
7366 functions for using libguestfs from Perl, including integration
