These functions may safely be used in a multi-threaded program if and only if they are called while the invoking thread owns the ( FILE *) object, as is the case after a successful call to the flockfile() or ftrylockfile() functions. If threads are disabled, then <> is equivalent to <>. RETURNS See <>. PORTABILITY POSIX 1003.1 requires <>. <> may be implemented as a macro.
