.SH DESCRIPTION
+.SS newpad
The \fBnewpad\fR routine creates and returns a pointer to a new pad data
structure with the given number of lines, \fInlines\fR, and columns,
\fIncols\fR.
Note that these
routines require additional parameters to specify the part of the pad to be
displayed and the location on the screen to be used for the display.
+.SS subpad
.PP
The \fBsubpad\fR routine creates and returns a pointer to a subwindow within a
pad with the given number of lines, \fInlines\fR, and columns, \fIncols\fR.
During the use of this routine, it will often be
necessary to call \fBtouchwin\fR or \fBtouchline\fR on \fIorig\fR before
calling \fBprefresh\fR.
+.SS prefresh, pnoutrefresh
.PP
The \fBprefresh\fR and \fBpnoutrefresh\fR routines are analogous to
\fBwrefresh\fR and \fBwnoutrefresh\fR except that they relate to pads instead
of windows.
The additional parameters are needed to indicate what part of the
pad and screen are involved.
-\fIpminrow\fR and \fIpmincol\fR specify the upper
+The \fIpminrow\fR and \fIpmincol\fR parameters specify the upper
left-hand corner of the rectangle to be displayed in the pad.
-\fIsminrow\fR,
-\fIsmincol\fR, \fIsmaxrow\fR, and \fIsmaxcol\fR specify the edges of the
+The \fIsminrow\fR,
+\fIsmincol\fR, \fIsmaxrow\fR, and \fIsmaxcol\fR
+parameters specify the edges of the
rectangle to be displayed on the screen.
The lower right-hand corner of the
rectangle to be displayed in the pad is calculated from the screen coordinates,
Negative values of
\fIpminrow\fR, \fIpmincol\fR, \fIsminrow\fR, or \fIsmincol\fR are treated as if
they were zero.
+.SS pechochar
.PP
The \fBpechochar\fR routine is functionally equivalent to a call to \fBaddch\fR
followed by a call to \fBrefresh\fR, a call to \fBwaddch\fR followed by a call
equivalents.
In the case of \fBpechochar\fR, the last location of the pad on
the screen is reused for the arguments to \fBprefresh\fR.
+.SS pecho_wchar
.PP
The \fBpecho_wchar\fR function is the analogous wide-character
form of \fBpechochar\fR.
.PP
X/Open does not define any error conditions.
