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.
