DESCRIPTION

Each of these functions has the same behaviour as its counterpart without the ’_unlocked’ suffix, except that they do not use locking (they do not set locks themselves, and do not test for the presence of locks set by others) and hence are thread-unsafe. See flockfile(3).

CONFORMING TO

The four functions getc_unlocked(), getchar_unlocked(), putc_unlocked(), putchar_unlocked() are in POSIX.1. The nonstandard *_unlocked() variants occur on a few Unix systems, and are available in recent glibc. They should probably not be used.
