\fBmvwdelch\fR - delete character under the cursor in a \fBcurses\fR window
|

|
|
.SH SYNOPSIS
|
|
|
|
|
\fB#include <curses.h>\fR
|
|
|
|
|
|
|
|
|
|
\fBint delch(void);\fR

|
|
.SH DESCRIPTION
|
|
|
|
|
These routines delete the character under the cursor; all characters to the
|
|
|
|
|
right of the cursor on the same line are moved to the left one position and the
|
|
|
|
|
last character on the line is filled with a blank. 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.
|
|
|
|
|
.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.
