41 The \fBadd_wch()\fR function writes a complex character to the \fBstdscr\fR
42 window at the current cursor position. The \fBmvadd_wch()\fR and
43 \fBmvwadd_wch()\fR functions write the character to the position indicated by
44 the \fIx\fR (column) and \fIy\fR (row) parameters. The \fBmvadd_wch()\fR
45 function writes the character to the \fBstdscr\fR window, while
46 \fBmvwadd_wch()\fR writes the character to the window specified by \fIwin\fR.
47 The \fBwadd_wch()\fR function is identical to \fBadd_wch()\fR, but writes the
48 character to the window specified by \fIwin\fR. These functions advance the
49 cursor after writing the character.
52 If \fIwch\fR is a spacing complex character, X/Open Curses replaces any
53 previous character at the specified location with \fIwch\fR (and its
54 rendition). If \fIwch\fR is a non-spacing complex character, X/Open Curses
55 preserves all existing characters at the specified location and adds the
56 non-spacing characters of \fIwch\fR to the spacing complex character. It
57 ignores the rendition associated with \fIwch\fR.
60 Characters that do not fit on the end of the current line are wrapped to the
61 beginning of the next line unless the current line is the last line of the
62 window and scrolling is disabled. In that situation, X/Open Curses discards
63 characters which extend beyond the end of the line.
66 When \fIwch\fR is a backspace, carriage return, newline, or tab, X/Open Curses
67 moves the cursor appropriately as described in the \fBcurses\fR(3XCURSES) man
68 page. Each tab character moves the cursor to the next tab stop. By default, tab
69 stops occur every eight columns. When \fIwch\fR is a control character other
70 than a backspace, carriage return, newline, or tab, it is written using
71 \fB^\fR\fIx\fR notation, where \fIx\fR is a printable character. When X/Open
72 Curses writes \fIwch\fR to the last character position on a line, it
73 automatically generates a newline. When \fI wch\fR is written to the last
74 character position of a scrolling region and \fBscrollok()\fR is enabled,
75 X/Open Curses scrolls the scrolling region up one line (see
76 \fBclearok\fR(3XCURSES)).
84 Is the character/attribute pair (rendition) to be written to the window.
93 Is a pointer to the window in which the character is to be written.
102 Is the y (row) coordinate of the character's position in the window.
111 Is the x (column) coordinate of the character's position in the window.
117 On success, these functions return \fBOK\fR. Otherwise, they return \fBERR\fR.
