.SH "NAME"
AppConfig::Sys \- Perl5 module defining platform\-specific information and methods for other AppConfig::* modules.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\&    use AppConfig::Sys;
\&    my $sys = AppConfig::Sys\->new();
\&
\&    @fields = $sys\->getpwuid($userid);
\&    @fields = $sys\->getpwnam($username);
.Ve
.SH "OVERVIEW"
.IX Header "OVERVIEW"
AppConfig::Sys is a Perl5 module provides platform-specific information and
operations as required by other AppConfig::* modules.
.PP
AppConfig::Sys is distributed as part of the AppConfig bundle.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
.SS "\s-1USING THE\s0 AppConfig::Sys \s-1MODULE\s0"
.IX Subsection "USING THE AppConfig::Sys MODULE"
To import and use the AppConfig::Sys module the following line should
appear in your Perl script:
.PP
.Vb 1
\&     use AppConfig::Sys;
.Ve
.PP
AppConfig::Sys is implemented using object-oriented methods.  A new
AppConfig::Sys object is created and initialised using the
AppConfig::Sys\->\fBnew()\fR method.  This returns a reference to a new
AppConfig::Sys object.
.PP
.Vb 1
\&    my $sys = AppConfig::Sys\->new();
.Ve
.PP
This will attempt to detect your operating system and create a reference to
a new AppConfig::Sys object that is applicable to your platform.  You may 
explicitly specify an operating system name to override this automatic 
detection:
.PP
.Vb 1
\&    $unix_sys = AppConfig::Sys\->new("Unix");
.Ve
.PP
Alternatively, the package variable \f(CW$AppConfig::Sys::OS\fR can be set to an
operating system name.  The valid operating system names are: Win32, \s-1VMS,\s0
Mac, \s-1OS2\s0 and Unix.  They are not case-specific.
.SS "AppConfig::Sys \s-1METHODS\s0"
.IX Subsection "AppConfig::Sys METHODS"
AppConfig::Sys defines the following methods:
.IP "\fBgetpwnam()\fR" 4
.IX Item "getpwnam()"
Calls the system function \fBgetpwnam()\fR if available and returns the result.
Returns undef if not available.  The \fBcan_getpwnam()\fR method can be called to
determine if this function is available.
.IP "\fBgetpwuid()\fR" 4
.IX Item "getpwuid()"
Calls the system function \fBgetpwuid()\fR if available and returns the result.
Returns undef if not available.  The \fBcan_getpwuid()\fR method can be called to
determine if this function is available.
