/** The application must define this variable, to contain the
 *    application name/identity.
 *
 * \ingroup group__frontend__stock_frontends
 *
 * The variable is an immutable array of <code>PAN_CHAR_T</code> (i.e. 
 * <code>char</code> in multibyte string builds, <code>wchar_t</code> in
 * wide string builds) whose name is non-mangled and has external linkage.
 *
 * Therefore, when defining within a C++ compilation unit it must be
 * declared <code>extern "C"</code>; when defined within a C compilation
 * unit it must be extern (optionally declared <code>extern</code>; it
 * must not be declared <code>static</code>).
 *
 * Examples:
\htmlonly
<pre>
  // C: multibyte string build
  char const                            PANTHEIOS_FE_PROCESS_IDENTITY[] = "my.app";

  // C++: wide string build
  extern "C" wchar_t const              PANTHEIOS_FE_PROCESS_IDENTITY[] = L"my.app";
</pre>
\endhtmlonly
 *
 * For convenience, the constructs PANTHEIOS_EXTERN_C, PAN_CHAR_T, and
 * PANTHEIOS_LITERAL_STRING() may be employed to write the variable
 * definition in a manner independent of language and/or character encoding,
 * as in:
\htmlonly
<pre>
  /\* C or C++; multibyte or wide string build \*\/
  PANTHEIOS_EXTERN_C PAN_CHAR_T const   PANTHEIOS_FE_PROCESS_IDENTITY[] = PANTHEIOS_LITERAL_STRING("my.app");

</pre>
\endhtmlonly
 *
 * \note The process identity must not contain any whitespace characters,
 *   otherwise Pantheios library initialisation will fail.
 *
 * \warn If you define the variable as a pointer
 *   (<code>PAN_CHAR_T const*</code>) the behaviour of the link unit is
 *   undefined.
 */

/* /////////////////////////////////////////////////////////////////////////
 * Application-defined functions
 */

/** \ref page__frontend__callbacks "Callback" function defined by the
 *    application, invoked during API initialisation.
 *
 * \ingroup group__frontend__stock_frontends
 *
 * \note This function is only required when the
 *   \ref page__frontend__callbacks "callback" version of the front-end
 *   library is used.
 *
 * \note This function *MUST NOT* throw an exception, and *MUST NOT* return
 *   <code>NULL</code>. If the implementation fails to acquire/produce the
 *   identity, it must call <code>pantheios_exitProcess(1)</code>. It may
 *   optionally call <code>pantheios_util_onBailOut4()</code> first.
