Description

Specifies the system's maximal supported path length.

The macro BOOST_PROCESS_POSIX_PATH_MAX is set to a positive integer value which specifies the system's maximal supported path length. It is only used if neither PATH_MAX nor _PC_PATH_MAX and HAVE_PATHCONF are defined. The maximal supported path length is required by boost::process::self::get_work_dir(). Please note that this function is also called by the constructor of boost::process::context.
