class myClass
{
stringstream ioss;
istream* is;
void f()

string initStr("");
ioss.str( initStr);
ioss.seekg( 0);
ioss.clear();
is->get( *ioss.rdbuf());
.....
}
public:
myClass( istream* is_): ioss(), is( is_) {}
....
};
works well, but:
void f()
{
....
// string initStr("");
ioss.str( ""); // HERE
ioss.seekg( 0);
ioss.clear();
is->get( *ioss.rdbuf());
.....
}
causes the program reproducible to fail.
Is there something obvious wrong? (compiles without warning)
Is there a easier/better/clearer way to reset a stringstream?
thanks,

Thank you, but it does not work.
The buffer is overridden, but the contents is kept:
FMTIn::GetLine: 1.
FMTIn::GetLine: 2.34.
FMTIn::GetLine: 5.34.
The stream (is) was:
1
2.34

How do you get rid the contents in a std::stringstream? I'm using one in a
for loop to format some status messages which I print to the screen. The
stringstream member function clear() only clears flags (bits) in the stream,
right? I solved it by declaring the stringstream inside the loop body even
though I have need of another stringstream just after the loop. So for each
iteration the constructor of the stringstream will be executed. Is...

Hi,
I believe that it should not be legal to create a vector (and array) of
stringstream since the copy constructor and assignment operators are
declared private. However, I don't understand why it shouldn't be
legal to create a vector (or array) or stringstream pointers. The
following code compiles and runs on g++, but seg faults while using the
Intel c++ compiler. Is this standard code? Which newsgroup (intel or
g++) needs to be...

Hi all!
I have a question about thread synchronization and c++ streams
(iostreams, stringstreams, etc). When optimizing a program for a
multicore processor I found that stringstream was causing a LOT of
synchronization overhead. After a bit of digging I concluded that this
synchronization has to do with the access to a global locale inside
the stream.
The problem can be seen by running the small distilled benchmark code

Hi,
I have a simple nit-picky question. It would be nice for a stringstream to have a member function which returns a C style string (just like a string does) so I could do this,

ss << "Etc...";
ss.c_str()

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
