These routines return a NULL-terminated array of chtype
quantities, starting at the current cursor position in the named
window and ending at the right margin of the window. The four
functions with n as the last argument, return a leading substring
at most n characters long (exclusive of the trailing (chtype)0).
Constants defined in <curses.h> can be used with the & (logical
AND) operator to extract the character or the attribute alone
from any position in the chstr [see curs_inch(3X)].
All routines return the integer ERR upon failure and an integer
value other than ERR upon successful completion (the number of
characters retrieved, exclusive of the trailing 0).
X/Open Curses defines no error conditions. In this
• If the win parameter is null, an error is returned,
• If the chstr parameter is null, an error is returned,
Functions with a “mv” prefix first perform a cursor movement
using wmove, and return an error if the position is outside the
window, or if the window pointer is null.
Note that all routines except winchnstr may be macros. SVr4 does
not document whether the result string is zero-terminated; it
does not document whether a length limit argument includes any
trailing 0; and it does not document the meaning of the return
These functions are described in the XSI Curses standard, Issue
4. It is no more specific than the SVr4 documentation on the
trailing 0. It does specify that the successful return of the
functions is OK.
