The cursor position does +not change (after moving to \fIy\fR, \fIx\fR, if specified). (This does not +imply use of the hardware delete character feature.) +.SH RETURN VALUE +All routines return the integer \fBERR\fR upon failure and an \fBOK\fR (SVr4 +specifies only "an integer value other than \fBERR\fR") upon successful +completion. +.PP +Functions with a "mv" prefix first perform a cursor movement using +\fBwmove\fP, and return an error if the position is outside the window, +or if the window pointer is null. +.SH NOTES +Note that \fBdelch\fR, \fBmvdelch\fR, and \fBmvwdelch\fR may be macros. +.SH PORTABILITY +These functions are described in the XSI Curses standard, Issue 4. The +standard specifies that they return \fBERR\fR on failure, but specifies no +error conditions. +.SH SEE ALSO +\fBcurses\fR(3X) |
