41  Some functions in the library set the global variable \c errno when an
42  error occurs. The file, \c <errno.h>, provides symbolic names for various
43  error codes.
44 
45  \warning The \c errno global variable is not safe to use in a threaded or
46  multi-task system. A race condition can occur if a task is interrupted
47  between the call which sets \c error and when the task examines \c
48  errno. If another task changes \c errno during this time, the result will
49  be incorrect for the interrupted task. */
