LIBRARY
Curses Library (libcurses)
DESCRIPTION
All of these routines copy wchstr, which points to a string of wchar_t
characters, directly into the window image structure starting at the
current or specified cursor position. The four routines with n as the
last argument copy at most n elements, but no more than will fit on the
line. If n=-1, then all the routines copy the whole string, to the max‐
imum number that fit on the line or until a null terminator is reached.
The routines do not advance the position of the window cursor. They
work faster than waddnwstr because they merely copy wchstr into the
window image structure. On the other hand, care must be taken when
using these functions because they: Do not perform any kind of checking
(such as for the newline character) Do not advance the current cursor
position Truncate the string, rather then wrapping it around to the new
line
NOTES
The header file <curses.h> automatically includes the header file
<stdio.h>.
Note that all routines except waddwchnstr may be macros.
The routines described on this reference page are among the MNLS Curses
functions that are not included in the X/Open Curses CAE specification.
MNLS routines are supported only for backward compatibility reasons.
For new applications, use the routines described on the add_wchstr(3)
reference page.
RETURN VALUES
All routines return the integer ERR upon failure and an integer value
other than ERR upon successful completion, unless otherwise noted in
the preceding routine descriptions.
