<hr><a name="_details"></a><h2>Detailed Description</h2>
When a function fails, <a class="el" href="group__brlapi__error.html#gf293f67c594571bb5ad6614eb22c0cb1">brlapi_errno</a> will hold an error code to explain why it failed. It should always be reported somehow.<p>
Although most errors are reported that way, some (called exceptions) are reported asynchronously for efficiency reasons, because they always just report a programming error. The affected functions are: brlapi_setFocus, brlapi_write* and brlapi_sendRaw. When they happen, the next call to brlapi_something will close the connection and call the <em>exception</em> handler. If the exception handler returns, the brlapi_something function will return an end-of-file error.<p>
The default exception handler (<a class="el" href="group__brlapi__error.html#g1e05f6233aab68e0aca7cd1470e92add">brlapi_defaultExceptionHandler()</a>) dumps the guilty packet before abort()ing. It can be replaced by calling <a class="el" href="group__brlapi__error.html#g7456fc847deec0762b939d44ed9868e9">brlapi_setExceptionHandler()</a>. For instance, the Java and Python bindings use this for raising a Java or Python exception that may be caught. <hr><h2>Define Documentation</h2>
