.SH PARAMETERS
.TP 20
\fIptfig\fP
Pointer to the figure in which the via should be added
.TP
\fIviatype\fP
Contact type
.TP
\fIx, y\fP
Coordinates of the center of the via.
.SH DESCRIPTION
\fBaddphvia\fP creates a new via whose center is at the given coordinates,
and adds it to the
list of vias pointed to by \fIptfig\->PHVIA\fP. The new via is 
added in front of the list, and becomes itself the list head.
.br
The parameters \fIviatype\fP, \fIx\fP and \fIy\fP fill respectivly
the \fITYPE\fP, \fIXVIA\fP and \fIYVIA\fP fields of the \fIphvia\fP structure.
.br
For a list of valid \fIviatype\fPs, and details on the structure, see
\fBphvia\fR(3).
.SH RETURN VALUE
\fBaddphvia\fP returns a pointer to the newly created via.
