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.

• 6.1 Standard Module os
• 6.2 Built-in Module time
• 6.3 Standard Module getopt
• 6.4 Standard Module tempfile
• 6.5 Standard Module errno
