strstream question

strstreams are deprecated in standard c++, they have been replaced with stringstreams.

#include<sstream>std::stringstream ss;ss << "Hello world";somefunc(ss.str().c_str());ss.str(std::string(""));ss << "Another hello world";somefunc(ss.str().c_str());

I cant directly help you, but...

isn't the <strstream> header deprecated now? seem to remember seeing that in MSVC, and 3.x GCC's

Try <sstream> - std::istringstream and std::ostringstream (iirc off the top of my head).

I think the two I just mentioned have methods to empty the buffers.

EDIT: Quant beat me by 28 seconds! But I'm sure theres a better way to reset the stream than he suggests.. but I suppose it still works.

Original post by grulim Hi anyone, I've code like this: strstream req1;req1 << "some text" << std::ends;someFunction(req1.str());strstream req2;req1 << "some other text" << std::ends;someFunction(req2.str()); i don't like using 2 strstream and i can't figure out how to empty req1. Some idea ? or am i doing something evil ;) ?

strstream::clear()?? Does it exist?

Well, with strstreams you need to do the following:

strstream s;s << some_stuff;char *c_string = s.str ();// do stuff with c_string// the .str () function above freezes the stream.// Not sure of the exact reason for this (memory allocation probably)// unfreeze the streams.freeze (false);// set write position back to the starts.seekp (0);

I try this solution, but does'nt seems to work :(
Anyways, i'll switch to stringstream.
Thank you, guy :)

Nothing says thanks quite like a good rating ;) [/hint]
