Name

DEFECT_OLD_STRINGSTREAM

Affected Systems-Compilers

Systems: all

Compilers: GNU C++ 2.7, SGI MipsPro 7.1nx

Description

The class strstream defined in the header file strstream or strstream.h has been deprecated by C++ Standardization committee. Its intended replacement is the class stringstream defined in the header file sstream. Most C++ compilers lack this new class, however. For all practical purposes, the two classes are the same, so strstream can be preprocessed to stand in for stringstream.

Work-Around

#if defined(DEFECT_OLD_STRINGSTREAM)
#include <strstream.h>
#define ostringstream ostrstream  // Avoid having two types where only one is required
#else // Standard C++
#include <sstream>
#endif

string result ;
ostringstream type_string ;
type_string << "some text" ;

#if defined(DEFECT_GCC27_STRINGSTREAM_STR)
  type_stream << '\0' ; \\ Manually null-terminate the stringstream
  result = string(type_stream.str()) ;
#else // Standard C++
  result = type_stream.str() ;
#endif
