Description:
Enable faster, non-thread-safe stdio functions if available,
globally throughout the package.
Files:
Depends-on:
unlocked-io-internal
configure.ac:
AC_DEFINE([GNULIB_STDIO_SINGLE_THREAD], [1],
[Define to 1 if you want the FILE stream functions getc, putc, etc.
to use unlocked I/O if available, throughout the package.
Unlocked I/O can improve performance, sometimes dramatically.
But unlocked I/O is safe only in single-threaded programs,
as well as in multithreaded programs for which you can guarantee that
every FILE stream, including stdin, stdout, stderr, is used only
in a single thread.])
AC_DEFINE([USE_UNLOCKED_IO], [GNULIB_STDIO_SINGLE_THREAD],
[An alias of GNULIB_STDIO_SINGLE_THREAD.])
