5151\brief Error code for last error encountered by library
5252
5353The variable \c errno holds the last error code encountered by
5454a library function. This variable must be cleared by the
5555user prior to calling a library function.
5656
5757\warning The \c errno global variable is not safe to use in a threaded or
5858multi-task system. A race condition can occur if a task is interrupted
5959between the call which sets \c error and when the task examines \c
6060errno. If another task changes \c errno during this time, the result will
6161be incorrect for the interrupted task. */
