int io_flag(const char *format, int row, int col, int* status, int radio);
io_flag() allows the user to make a single true/false selection. "status" points to the status of the selection, that can be zero or non-zero. If "status" is initially set to anything but zero, io_flag() corrects value to one. "format" holds the shape of the checkbox as io_displayflag() function.
io_flag() begins the selection by displaying the checkbox according to its “*status”. (Remember that the value of "*status" is corrected before the editing begins). Then the function waits for the user input.
- If the user input is any of the printable keys (' ' <>
- If the user input is SPACE:
- If “radio” is true, then the *status is set to one, checkbox is displayed and function is terminated returning space.
- If “radio” is false, then the value of *status is toggled between 0 and 1, the checkbox is displayed and function is exited returning space.
So, i'm just going to jot down what I need to do here instead of using notepad.
- If status is anything but 0, turns it into 1
- format holds same shape of checkbox as io_displayflag
- If the user input is any of the printable keys (' ' < key <= '~') excluding space, it should be ignored (no action taken).
- If the user input is any of the function keys, the function is terminated returning the key.
