These routines insert a wchar_t character string (as many characters as will fit on the line) before the character under the cursor. All characters to the right of the cursor are shifted right, with the possibility of the rightmost characters on the line being lost. No wrapping is performed. The cursor position does not change (after moving to y, x, if specified). The four routines with n as the last argument insert a leading substring of at most n wchar_t characters. If n is less than 1, the entire string is inserted.
If a character in wstr is a tab, newline, carriage return or backspace, the cursor is moved appropriately within the window. A newline also does a clrtoeol before moving. Tabs are considered to be at every eighth column. If a character in wstr is another control character, it is drawn in the ^X notation. Calling win_wch after adding a control character (and moving to it, if necessary) does not return the control character, but instead returns a character in the ^-representation of the control character.
Note that all but wins_nwstr may be macros.
If the first character in the string is a nonspacing character, these functions will fail. XSI does not define what will happen if a nonspacing character follows a control character.
Upon successful completion, these functions return OK. Otherwise, they return ERR.
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.
