/*!
The function ex_opts() is used to set message reporting options.

\return Returns previous value for the message reporting option.

\param[in] options   Integer option value. Current options are shown in the
table below.

<table>
<tr><td> #EX_ABORT  </td><td> Causes fatal errors to force program
                                exit. (Default is false.) </td></tr>
<tr><td> #EX_DEBUG  </td><td> Causes certain messages to print
                                for debug use. (Default is false.)</td></tr>
<tr><td> #EX_VERBOSE</td><td> Causes all error messages to print when true,
                                otherwise no error messages will print. (Default
is false.)</td></tr>
</table>

\note Values may be OR'ed together to provide any combination
      of these capabilities.

For example, the following will cause all messages to print
and will cause the program to exit upon receipt of fatal error:

~~~{.c}
#include "exodusII.h"
ex_opts(EX_ABORT|EX_VERBOSE);
~~~
