c - Are temporary values like operands of arithmetic operators put in the stack? -

-

i know happens in memory when use arithmetics operators like:

int i; = 5 + 3;

will values 5 , 3 automatically put stack temporarily (like if static variables automatically created them)? suppose need exist somewhere addition happen, where?

what happens when there function call involved?

i = 5 + f(3);

is argument 3 passed f stored somewhere? , return value of f (say f returns int)?

many thanks,

your first example evaluated @ compile-time (see http://en.wikipedia.org/wiki/constant_folding), let's ignore one.

in case of i = f(3) + g(5), compiler has many choices on how implement this, depending on particular platform you're working on. may put things in registers, or on stack, or elsewhere, sees fit.

java - SNMP4J General Variable Binding Error -

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
