Writes a character to the console without locking the thread.
_putch_nolock and _putwch_nolock are identical to _putch and _putwch, respectively, except that they are not protected from interference by other threads. They might be faster because they do not incur the overhead of locking out other threads. Use these functions only in thread-safe contexts such as single-threaded applications or where the calling scope already handles thread isolation.
