The old "raw" function becomes get_key_init. Calling get_key_init is
only necessary if one wants to control the moment standard input is
switched to raw mode. If get_key is invoked without a prior call to
get_key_init, it will initialize automatically.
- atrf-path/gui.c (raw, main): renamed "raw" to get_key_init
- atrf-path/gui.c (old_term, restore_term, get_key_init, get_key):
moved to include/getkey.h and lib/getkey.c
- lib/getkey.c (get_key_init, get_key): made calling get_key_init
optional
- lib/Makefile (OBJS): added getkey.o
