C++ (Cpp) _FPOSOFF Examples

Example #1

File: positioning.hpp Project: eagle-dai/external-libs

// Converts a std::fpos_t to a stream_offset
inline stream_offset fpos_t_to_offset(std::fpos_t pos)
{
#  if defined(_POSIX_) || (_INTEGRAL_MAX_BITS >= 64) || defined(__IBMCPP__)
    return pos;
#  else
    return _FPOSOFF(pos);
#  endif
}

Example #2

File: positioning.hpp Project: eagle-dai/external-libs

inline stream_offset position_to_offset(std::streampos pos)
{
    return fpos_t_to_offset(streampos_to_fpos_t(pos)) +
        static_cast<stream_offset>(
            static_cast<std::streamoff>(pos) -
            _FPOSOFF(streampos_to_fpos_t(pos))
        );
}

Example #3

File: positioning.hpp Project: AlexS2172/IVRM

inline stream_offset fpos_t_to_offset(std::fpos_t pos)
{ // Helper function.
#if defined(_POSIX_) || (_INTEGRAL_MAX_BITS >= 64)
    return pos;
#else
    return _FPOSOFF(pos);
#endif
}

Example #4

File: StdLibFileIO.cpp Project: zhaojunlucky/veda

int CStdLibFileIO::GetPosition()
{
    fpos_t fPosition;

    memset(&fPosition, 0, sizeof(fPosition));
    fgetpos(m_pFile, &fPosition);
   
    return _FPOSOFF(fPosition);
}
