+Error handling:
+-------------
+
+We ask to use one single return point in a function. For that, we uses the
+"goto" statement for the error handling creating one single point for error
+handling and return code. See the following example:
+
+int some_function(...)
+{
+ int ret;
+ [...]
+
+ if (ret != 0) {
+ goto error;
+ }
+
+ [...]
+error:
+ return ret;
+}
