Author: russell

New Revision: 62093

URL: http://svn.digium.com/view/asterisk?view=rev&rev=62093
Log:
Instead of specifying a result number of 0 to get the number of available
results, make it be "getnum".  Updated example usage ...

exten => s,1,Set(ID=${DUNDIQUERY(1234)})
exten => s,n,Set(NUMRESULTS=${DUNDIRESULT(${ID}|getnum)})
exten => s,n,Set(X=1)
exten => s,n,While($[${X} <= ${NUMRESULTS}])
exten => s,n,NoOp(Result ${X} is ${DUNDIRESULT(${ID}|${X})})
exten => s,n,Set(X=$[${X} + 1])
exten => s,n,EndWhile
