The scanw() function is the same as the scanf() function, excepting that the input data stream is read from the current cursor position on stdscr,

The wscanw() function is the same as the scanw() function, excepting that the data stream is read from the window specified by win.

The mvscanw() and mvwscanw() functions are the same as the scanw() and mvscanw() functions, respectively, excepting that wmove() is called to move the cursor to the position specified by y, x before the data is read from the window.

RETURN VALUES

Functions returning pointers will return NULL if an error is detected. The functions that return an int will return one of the following values:

OK

The function completed successfully.
