.SH DESCRIPTION
.IX Header "DESCRIPTION"
Provides a perl interface to the \f(CWlchown()\fR system call, on platforms that
support it.
.SH "DEFAULT EXPORTS"
.IX Header "DEFAULT EXPORTS"
The following symbols are exported be default:
.IP "lchown (LIST)" 4
.IX Item "lchown (LIST)"
Like the \f(CW\*(C`chown\*(C'\fR builtin, but using the \f(CWlchown()\fR system call so that
symlinks will not be followed.  Returns the number of files successfully
changed.
.Sp
On systems without the \f(CWlchown()\fR system call, \f(CW\*(C`lchown\*(C'\fR always returns
\&\f(CW\*(C`undef\*(C'\fR and sets \f(CW\*(C`errno\*(C'\fR to \f(CW\*(C`ENOSYS\*(C'\fR (Function not implemented).
.SH "ADDITIONAL EXPORTS"
.IX Header "ADDITIONAL EXPORTS"
The following symbols are available for export but are not exported by
default:
.IP "LCHOWN_AVAILABLE ()" 4
.IX Item "LCHOWN_AVAILABLE ()"
Returns true on platforms with the \f(CWlchown()\fR system call, and false on
platforms without.
