/* These are wrappers for functions/macros from the GNU C library, and
|
|
from other C libraries supporting POSIX's optional thread-safe functions.
|
|
|
|
The standard I/O functions are thread-safe. These *_unlocked ones are
|
|
more efficient but not thread-safe. That they're not thread-safe is
|
|
fine since all of the applications in this package are single threaded.
|
|
|
|
Also, some code that is shared with the GNU C library may invoke
|
|
the *_unlocked functions directly. On hosts that lack those
|
|
functions, invoke the non-thread-safe versions instead. */
