Restores soft function-key labels to the screen.
Curses Library (libcurses.a)
#include <curses.h>
slk_restore()
The slk_restore subroutine restores the soft function-key labels to the screen after a call to the slk_clear subroutine. The label names are not restored. These labels appear at the bottom of the screen and give applications, such as editors, a more user-friendly look. You must call the slk_init subroutine before you can use soft labels.
