NAME
       linenum - Line number entries in an object file

DESCRIPTION
       When  invoked  with  the -g option, the cc(1) command generates an entry in the object file for each C source line on which a breakpoint is
       possible.  Users can then reference line numbers when debugging. (See dbx(1).)
