Error reporting.
<p>
Types and functions related to reporting errors.<p>
In essence D-Bus error reporting works as follows:<p>
<div class="fragment"><pre class="fragment"> <a class="code" href="structDBusError.html">DBusError</a> error;
<a class="code" href="group__DBusErrors.html#g8ce28eae754237703296599967d7ab77">dbus_error_init</a> (&error);
dbus_some_function (arg1, arg2, &error);
<span class="keywordflow">if</span> (<a class="code" href="group__DBusErrors.html#g49c2509c79ae0fa01f5004b17e2ec6be">dbus_error_is_set</a> (&error))
{
fprintf (stderr, <span class="stringliteral">"an error occurred: %s\n"</span>, error.message);
<a class="code" href="group__DBusErrors.html#gd192d53cf930b1b12e1ce91bc0963709">dbus_error_free</a> (&error);
}
</pre></div><p>
By convention, all functions allow <a class="el" href="group__DBusMacros.html#g070d2ce7b6bb7e5c05602aa8c308d0c4">NULL</a> instead of a DBusError*, so callers who don't care about the error can ignore it.<p>
There are some rules. An error passed to a D-Bus function must always be unset; you can't pass in an error that's already set. If a function has a return code indicating whether an error occurred, and also a <a class="el" href="structDBusError.html">DBusError</a> parameter, then the error will always be set if and only if the return code indicates an error occurred. i.e. the return code and the error are never going to disagree.<p>
An error only needs to be freed if it's been set, not if it's merely been initialized.<p>
You can check the specific error that occurred using <a class="el" href="group__DBusErrors.html#gd4a073fdbcfe5170ebb984fb79c7a94f">dbus_error_has_name()</a>.<p>
Errors will not be set for programming errors, such as passing invalid arguments to the libdbus API. Instead, libdbus will print warnings, exit on a failed assertion, or even crash in those cases (in other words, incorrect use of the API results in undefined behavior, possibly accompanied by helpful debugging output if you're lucky). <hr><h2>Function Documentation</h2>

The format may be <a class="el" href="group__DBusMacros.html#g070d2ce7b6bb7e5c05602aa8c308d0c4">NULL</a>, which means a (pretty much useless) default message will be deduced from the name. This is not a good idea, just go ahead and provide a useful error message. It won't hurt you.<p>
If no memory can be allocated for the error message, an out-of-memory error message will be set instead.<p>
