.I mapname
.SH Description
.NXR "yppoll command"
.NXAM "ypfiles file" "yppoll command"
.NXR "YP map" "determining version"
The
.PN yppoll 
command asks a 
.PN ypserv 
process what the order number is, and which host
is the master YP server for the named map.  
If the server is a
v.1 YP protocol server, 
.PN yppoll
uses the older protocol to communicate with 
.PN ypserv 
and uses the older diagnostic messages if a failure occurs.
.SH Options
.IP "\fB\-h \fIhost\fR"
Ask the 
.PN ypserv 
process at
.I host
about the map parameters.  If 
.I host 
is not specified, the YP server for the local host is used.
That is, the default host is the one returned by 
.MS ypwhich 1yp .
.IP "\fB\-d \fIdomain\fR"
Use
.I domain
instead of the default domain.
