i have a simply code to write a string to an ostream:
bool CXXStreamTools::WriteString(ostream &os,string Value)
{
try
{
long len = Value.size()+1;
os.write(reinterpret_cast<char *> (&len),sizeof(len));
os.write(reinterpret_cast<char *> ((char
*)Value.c_str()),len);
}
catch(...)
{
return false;
}
return true;
}
it works fine.
How can i write (or read) a wstring instead of a string to the same
ostream ?
Just change the first line to
long len = (Value.size()+1) * sizeof(wstring::value_type);
If you are actually going to write a mix of narrow and wide strings to
the same stream, it's not clear how you plan to figure out which is
which when you read them back.
Yes, i have a mix. I devide them by chunk-id?s.
Thanks, Igor.
