* Some functions in the library set the global variable @c errno when an
* error occurs. The file, @c <errno.h>, provides symbolic names for various
* error codes.
*
* @warning The @c errno global variable is not safe to use in a threaded or
* multi-task system. A race condition can occur if a task is interrupted
* between the call which sets @c error and when the task examines @c
* errno. If another task changes @c errno during this time, the result will
* be incorrect for the interrupted task.
