.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Modules that provide OS-specific behaviors often need to know if
the current operating system matches a more generic type of
operating systems. For example, 'linux' is a type of 'Unix' operating system
and so is 'freebsd'.
.PP
This module provides a mapping between an operating system name as given by
\&\f(CW$^O\fR and a more generic type.  The initial version is based on the \s-1OS\s0 type
mappings provided in Module::Build and ExtUtils::CBuilder.  (Thus,
Microsoft operating systems are given the type 'Windows' rather than 'Win32'.)
.SH "USAGE"
.IX Header "USAGE"
No functions are exported by default. The export tag \*(L":all\*(R" will export
all functions listed below.

\&  $os_type = os_type(\*(AqMSWin32\*(Aq);
.Ve
.PP
Returns a single, generic \s-1OS\s0 type for a given operating system name.  With no
arguments, returns the \s-1OS\s0 type for the current value of \f(CW$^O\fR.  If the
operating system is not recognized, the function will return the empty string.
.SS "\fBis_os_type()\fP"
.IX Subsection "is_os_type()"
.Vb 2
\&  $is_windows = is_os_type(\*(AqWindows\*(Aq);
\&  $is_unix    = is_os_type(\*(AqUnix\*(Aq, \*(Aqdragonfly\*(Aq);
.Ve
.PP
Given an \s-1OS\s0 type and \s-1OS\s0 name, returns true or false if the \s-1OS\s0 name is of the
given type.  As with \f(CW\*(C`os_type\*(C'\fR, it will use the current operating system as a
default if no \s-1OS\s0 name is provided.
