6. Generic Operating System Services

The modules described in this chapter provide interfaces to operating system features that are available on (almost) all operating systems, such as files and a clock. The interfaces are generally modelled after the Unix or C interfaces but they are available on most other systems as well. Here's an overview:

os

-- Miscellaneous OS interfaces.

time

-- Time access and conversions.

getopt

-- Parser for command line options.

tempfile

-- Generate temporary file names.

errno

-- Standard errno system symbols.

glob

-- Unix shell style pathname pattern expansion.

fnmatch

-- Unix shell style pathname pattern matching.

locale

-- Internationalization services.
