The host environment is the set of resources, such as the filesystem, network and processes, that are managed by the operating system within which a Scheme program is executing. This SRFI specifies how the host environment can be accessed from within a Scheme program. It does so by leveraging widespread support for POSIX, the Portable Operating System Interface standardized by the IEEE. Not all the functions of this SRFI are available on all operating systems.
