protected virtual member function
<sstream>
streambuf* setbuf (char* s, streamsize n);
Set buffer
Virtual function called by the public member function pubsetbuf to influence the object in a way that is dependent on the library implementation.
If both arguments are zero, the call is guaranteed to have no effect on the stringbuf object.
Parameters
- s, n
- Implementation-defined.
If both are zero, no effect.
streamsize is a signed integral type.
Return Value
Returns this.
Data races
If both arguments are zero, it introduces no data races.
Otherwise, unspecified.
Exception safety
Basic guarantee: if an exception is thrown, the object is in a valid state.
