示例1: test_seekable_in_chars
bool test_seekable_in_chars(std::iostream& io)
{
int i; // old 'for' scope workaround.
// Test seeking with ios::cur
for (i = 0; i < data_reps; ++i) {
int j;
for (j = 0; j < chunk_size; ++j)
io.put(narrow_data()[j]);
io.seekp(-chunk_size, BOOST_IOS::cur);
for (j = 0; j < chunk_size; ++j)
if (io.get() != narrow_data()[j])
return false;
io.seekp(-chunk_size, BOOST_IOS::cur);
for (j = 0; j < chunk_size; ++j)
io.put(narrow_data()[j]);
}
// Test seeking with ios::beg
std::streamoff off = 0;
io.seekp(0, BOOST_IOS::beg);
for (i = 0; i < data_reps; ++i, off += chunk_size) {
int j;
for (j = 0; j < chunk_size; ++j)
io.put(narrow_data()[j]);
io.seekp(off, BOOST_IOS::beg);
for (j = 0; j < chunk_size; ++j)
if (io.get() != narrow_data()[j])
return false;
io.seekp(off, BOOST_IOS::beg);
for (j = 0; j < chunk_size; ++j)
io.put(narrow_data()[j]);
}
// Test seeking with ios::end
io.seekp(0, BOOST_IOS::end);
off = io.tellp();
io.seekp(-off, BOOST_IOS::end);
for (i = 0; i < data_reps; ++i, off -= chunk_size) {
int j;
for (j = 0; j < chunk_size; ++j)
io.put(narrow_data()[j]);

}
return true;
}示例2: GetAsString
std::string StringUtilities::GetAsString(std::iostream& i_stream)
{
int length;
char* p_buffer;
// get length of file:
i_stream.seekg (0, std::iostream::end);
length = static_cast<int>(i_stream.tellg());
i_stream.seekg (0, std::iostream::beg);
// allocate memory:
p_buffer = new char [length];
//write file
int pos = 0;
while(i_stream.good())
{
p_buffer[pos] = i_stream.get();
++pos;
}
std::string out(p_buffer, pos);
delete[] p_buffer;
return out;
