LLFIO can't map files when running under Jenkins on Windows #163
Description
I think because Jenkins is a service.
I run:
if (auto ph = llfio::path_handle::path(temp_dir.path)) {
if (auto f = llfio::mapped_uniquely_named_file(
4096, ph.value(), llfio::mapped_file_handle::mode::write,
llfio::mapped_file_handle::caching::temporary,
llfio::mapped_file_handle::flag::unlink_on_first_close)) {
if (auto r = f.value().truncate(1)) {
which fails with path not found in the truncate.
Here's a trace:

Seems like \Sessions\0\BaseNamedObjects* is not the right path in this windows service context.
