okay hate ask question ... here goes. writing code in c on x86 machine. want send struct on network , and want convert struct network byte order ... understand drama packing , the gcc packing pragmas ... want know how convert struct (or array or such arbitrary memory blob) network byte order. is there standard (unix/linux/posix) function call can use or must roll own. x in principle, can go through struct , call htonl or htons on each uint32_t or uint16_t field, respectively, assigning results or copy of struct. however, not recommend sort of approach. it's fragile , subject struct alignment issues, etc. unless transmitting , receiving data extremely performance-critical, implement proper serialize , deserialize methods structures. can write numeric values out 1 byte @ time in binary format, choosing whether want write least significant or significant part first. really, recommend choosing modern text-based serialization format json or (uhg, hate this) xml. c...

i working on java web app uses struts 2 rest plugin. convention, url ends ".xml" sent through xstreamhandler. fine--it's want in cases. but in small number of cases want stream xml browser. know how set @result(type="stream") annotation , make return inputstream. i've done images in other parts of app. problem returning xml stream rest plugin sees caller requesting xml tries deserialize action class instead of streaming out inputstream. how can tell rest plugin, in these few special cases, not send xml result through xstreamhandler? thanks! oh, cool, figured out answer. secret return instance of class implements com.opensymphony.xwork2.result . assuming 'getfilename()' returns name of xml file want stream: @skipvalidation public com.opensymphony.xwork2.result streamfile() throws filenotfoundexception { return new streamresult(new fileinputstream(new file(getfilename()))); }

c++ specifically, if matters, imagine answer lies in assembly code somehow. if have multiple blocks in common scope (say, function) each use variable of same type, faster define variable in common scope , reinitialise in each block, or redefine , initialise in each of blocks (or there no fundamental difference)? example: int i; {//block 1 = somefunction(); ... } {//block 2 = someotherfunction(); ... } versus {//block 1 int = somefunction(); ... } {//block 2 int = someotherfunction(); ... } if i pod type (like int shown in example), there no difference @ all. if i of type has nontrivial constructor or assignment operator exciting, there might huge difference , you'd have compare appropriate constructors , assignment operators do. if both blocks entered, you'll need consider destructor well. in general, shouldn't worry it. take cleaner approach , declare variable in restricted scope possible, close first us...
