All of these routines copy chstr 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, up 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
waddnstr
because they merely copy
chstr
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 a new
line
The header file <curses.h> automatically includes the header file <stdio.h>.
Note that all routines except
waddchstr
and
waddchnstr
may be macros.
All routines return the integer
ERR
upon
failure and
OK
upon successful completion.
