Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

Go to file
Jim Meyering a178a4e7bf Move safewrite and saferead to a separate file. 
We currently use safewrite from inside libvirt and don't want to publish
any such function name.  However, we do want to use it in applications
like virsh, libvirtd and libvirt_proxy that link with libvirt.  To that
end, this change moves that function definition (along with the nearly
identical saferead) into a new file, util-lib.c.  To avoid maintaining
separate copies of even such small functions, we simply include that new
file from util.c.  Then, the separate applications that need to use
safewrite simply compile and link with util-lib.c.

Of course, this does mean that each of those applications will
containing two copies of these functions.  However, the functions
are so small that it's not worth worrying about that.

* src/util.c (saferead, safewrite): Move function definitions to
util-lib.c and include that .c file.
* src/util-lib.c (saferead, safewrite): New file.  Functions from src/util.c
with slight change (s/int r =/ssize_t r =/) to reflect read/write return type.
* src/util-lib.h: Declare the two moved functions.
* src/util.h: Remove declarations.  Include src/util-lib.h.
* proxy/Makefile.am (libvirt_proxy_SOURCES): Add src/util-lib.c.
* qemud/Makefile.am (libvirtd_SOURCES): Likewise.
* src/Makefile.am (virsh_SOURCES): Add util-lib.c.  Remove some SP-before-TAB.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
