A pad is like a window, except that it is not restricted by the +screen size, and is not necessarily associated with a particular part of the +screen. Pads can be used when a large window is needed, and only a part of the +window will be on the screen at one time. Automatic refreshes of pads +(\fIe\fR.\fIg\fR., from scrolling or echoing of input) do not occur. It is not +legal to call \fBwrefresh\fR with a \fIpad\fR as an argument; the routines +\fBprefresh\fR or \fBpnoutrefresh\fR should be called instead. 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. + +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. +Unlike \fBsubwin\fR, which uses screen coordinates, the window is at position +(\fIbegin\fR_\fIx\fR\fB,\fR \fIbegin\fR_\fIy\fR) on the pad. The window is +made in the middle of the window \fIorig\fR, so that changes made to one window +affect both windows. 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. + +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 +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 +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, +since the rectangles must be the same size. Both rectangles must be entirely +contained within their respective structures. Negative values of +\fIpminrow\fR, \fIpmincol\fR, \fIsminrow\fR, or \fIsmincol\fR are treated as if +they were zero. + +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 +to \fBwrefresh\fR, or a call to \fBwaddch\fR followed by a call to +\fBprefresh.\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. In the case of \fBpechochar\fR, the last location of the pad on +the screen is reused for the arguments to \fBprefresh\fR. +.SH RETURN VALUE +Routines that return an integer return \fBERR\fR upon failure and \fBOK\fR +(SVr4 only specifies "an integer value other than \fBERR\fR") upon successful +completion. + +Routines that return pointers return \fBNULL\fR on error, and set \fBerrno\fR +to \fBENOMEM\fR. +.SH NOTES +Note that \fBpechochar\fR may be a macro. +.SH PORTABILITY +The XSI Curses standard, Issue 4 describes these functions. +.SH SEE ALSO +\fBcurses\fR(3X), \fBcurs_refresh\fR(3X), \fBcurs_touch\fR(3X), \fBcurs_addch\fR(3X). +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
