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 maximum 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
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, Compaq
recommends the use of the routines described on the
add_wchstr(3)
reference
page.
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.
