Its function is similar to that of \fBputchar()\fR. At the right margin, an automatic newline is performed. At the bottom of the scrolling region, if \fBscrollok()\fR is enabled, the scrolling region is scrolled up one line. .sp .LP If \fIch\fR is a tab, newline, or backspace, the cursor is moved appropriately within the window. A newline also does a \fBclrtoeol()\fR before moving. Tabs are considered to be at every eighth column. If \fIch\fR is another control character, it is drawn in the \fB^\fR\fIX\fR notation. Calling \fBwinch()\fR after adding a control character does not return the control character, but instead returns the representation of the control character. See \fBcurs_inch\fR(3CURSES). .sp .LP Video attributes can be combined with a character by OR-ing them into the parameter. This results in these attributes also being set. (The intent here is that text, including attributes, can be copied from one place to another using \fBinch()\fR and \fBaddch()\fR.) (see \fBstandout()\fR, predefined video attribute constants, on the \fBcurs_attr\fR(3CURSES) page). .sp .LP The \fBechochar()\fR and \fBwechochar()\fR routines are functionally equivalent to a call to \fBaddch()\fR followed by a call to \fBrefresh()\fR, or a call to \fBwaddch\fR followed by a call to \fBwrefresh()\fR. The knowledge that only a single character is being output is taken into consideration and, for non-control characters, a considerable performance gain might be seen by using these routines instead of their equivalents. .SS "Line Graphics" .sp .LP The following variables may be used to add line drawing characters to the screen with routines of the \fBaddch()\fR family. When variables are defined for the terminal, the \fBA_ALTCHARSET\fR bit is turned on (see \fBcurs_attr\fR(3CURSES)). Otherwise, the default character listed below is stored in the variable. The names chosen are consistent with the VT100 nomenclature. .sp .sp .TS tab() box; cw(1.83i) |cw(1.25i) |cw(2.42i) lw(1.83i) |lw(1.25i) |lw(2.42i) .
