Description:
|
|
These routines write a chtype or cchar_t string directly into
|
|
the window structure, starting at the current or specified
|
|
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 the whole string is copied, up to the maximum number
|
|
that will fit on the line.
|
|
|
|
The cursor position is not advanced. These routines do not check
|
|
for newline or other special characters, nor does any line
|
|
wrapping occur.
|
|
|
|
Return Value:
|
|
All functions return OK or ERR.
