Возвращаемое значение (Return value)

All routines return the integer OK on success, or ERR on failure.

X/Open does not define any error conditions.

This implementation

• returns an error if the window pointer is null.

• returns an error if the color pair parameter for wcolor_set is outside the range 0..COLOR_PAIRS-1.

• does not return an error if either of the parameters of wattr_get used for retrieving attribute or color-pair values is NULL.

Functions with a 'mv' prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null.
