+
+    <para><function>sd_bus_can_send()</function> is mostly used for checking if file descriptor

+    <title>Return Value</title>
+
+    <para>On failure, <function>sd_bus_can_send()</function> returns a negative errno-style error
+    code. If values of the given type can be sent over the given bus, it returns a positive integer.
+    Otherwise, it returns zero.</para>
