<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Error handling of the m17n library. </p>
<p>There are two types of errors that may happen in a function of the m17n library.</p>
<p>The first type is argument errors. When a library function is called with invalid arguments, it returns a value that indicates error and at the same time sets the external variable <a class="el" href="group__m17nError.html#ga995a2e373cfd6a8e5eaca8686b5b0a73" title="External variable to hold error code of the m17n library.">merror_code</a> to a non-zero integer.</p>
<p>The second type is memory allocation errors. When the required amount of memory is not available on the system, m17n library functions call a function pointed to by the external variable <code>m17n_memory_full_handler</code>. The default value of the variable is a pointer to the default_error_handle() function, which just calls <code> exit()</code>. </p>
