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. */
