2.6 'gawk''s Exit Status
========================

If the 'exit' statement is used with a value (*note Exit Statement::),
then 'gawk' exits with the numeric value given to it.

   Otherwise, if there were no problems during execution, 'gawk' exits
with the value of the C constant 'EXIT_SUCCESS'.  This is usually zero.

   If an error occurs, 'gawk' exits with the value of the C constant
'EXIT_FAILURE'.  This is usually one.

   If 'gawk' exits because of a fatal error, the exit status is two.  On
non-POSIX systems, this value may be mapped to 'EXIT_FAILURE'.
