Consider the following inverted call tree (effectively a dependency tree
-- callees are at the top and near the left margin):
lazy_make_tmpdir() [lib/tmpdirs.c]
guestfs_int_lazy_make_tmpdir() [lib/tmpdirs.c]
guestfs_int_make_temp_path() [lib/tmpdirs.c]
guestfs_int_lazy_make_sockdir() [lib/tmpdirs.c]
guestfs_int_create_socketname() [lib/launch.c]
lazy_make_tmpdir() is our common workhorse / helper function that
centralizes the mkdtemp() function call.
guestfs_int_lazy_make_tmpdir() and guestfs_int_lazy_make_sockdir() are the
next level functions, both calling lazy_make_tmpdir(), just feeding it
different dirname generator functions, and different "is_runtime_dir"
qualifications. These functions create temp dirs for various, more
specific, purposes (see the manual and "lib/guestfs-internal.h" for more
details).
On a yet higher level are guestfs_int_make_temp_path() and
guestfs_int_create_socketname() -- they serve for creating *entries* in
those specific temp directories.
The discrepancy here is that, although all the other functions live in
"lib/tmpdirs.c", guestfs_int_create_socketname() is defined in
"lib/launch.c". That makes for a confusing code reading; move the function
to "lib/tmpdirs.c", just below its sibling function
guestfs_int_make_temp_path().
While at it, correct the leading comment on
guestfs_int_create_socketname() -- the socket pathname is created in the
socket directory, not in the temporary directory.
