Lock the specified section of the file that the file object is
referring to. The arguments \code{\var{len}}, \code{\var{start}}
and \code{\var{whence}} are optional with the understanding that
if \code{\var{start}} is used \code{\var{len}} becomes mandatory,
and if \code{\var{whence}} is used \code{\var{len}} and
\code{\var{start}} become mandatory. The format is explained
below in a table. The length argument specifies the length of the
section that should be locked. The default is \code{0}. The start
specifies the starting offset of the section. The default is
\code{0}. The whence argument specifies where the offset is
referring to. The format is explained
below in a table. The \var{len} argument specifies the length of the
section that should be locked. The default is \code{0}. \var{start}
specifies the starting offset of the section, where the default is
\code{0}. The \var{whence} argument specifies where the offset is
relative to. It accepts one of the constants \code{SEEK_SET},
\code{SEEK_CUR} or \code{SEEK_END}. The default is \code{SEEK_SET}.
