| /* 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. */ |
