	Returns a unique per-process temporary folder. The top level temporary folder will be automatically destroyed if the process ends properly. More...
static FWTOOLS_API int	tempFolderPID (const ::boost::filesystem::path &dir) noexcept
	Returns the pid of a temporary folder If the given folder contains a file matching *.pid and the first part of the file name is a integer, this method will return this number. Otherwise, zero will be returned.
