[Libguestfs] [PATCH 1/4] New internal function guestfs___print_timestamped_argv

This function generalises the existing print_cmdline used to output the qemu command line to output any given command line, and exports it to other modules. It also adds a timestamp to the old print_cmdline output for consistency with guestfs___print_timestamped_message. --- src/guestfs-internal.h | 1 + src/launch.c | 48 ++++++++++++++++++++++++------------------------ 2 files changed, 25 insertions(+), 24 deletions(-)
