|
|
* 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.
