,
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

NULL
if an
error is detected. The functions that return an int will return one of the
