if (origin == SEEK_CUR)
stream.seekp(v, std::ios_base::cur);
else if (origin == SEEK_END)
stream.seekp(v, std::ios_base::end);
else

}示例2: sendBuffer
Variant ClientBase::sendBuffer(char type, RequestID requestID, std::ostringstream &stream)
{
unsigned int size = (unsigned int)stream.tellp();
size -= sizeof(size);
stream.seekp(0);
stream.write((const char*)&size, sizeof(size));

}示例3: expand
std::string expand(Range const& key)
{
thread_local std::ostringstream oss;
oss.str().clear();
oss.clear();

}示例4: Journal
ostream & Journal(entier level)
{
if (level <= journal_level) {
cerr << "[" << level << "] ";
return cerr;
} else {
junk_journal.seekp(0);
return junk_journal;

}示例5: to_binary
std::string to_binary(std::ostringstream &out, const T &t) {
out.clear();
out.seekp(0);
bf::fold(t, 0, app_item(out));
// because out.str() gives us the contents of the string buffer,
// not the contents written since clear() was called, we need to
// chop off any remaining garbage at the end.
std::string rv = out.str();
rv.resize(out.tellp());
return rv;
}示例6: write_playlist_segment
u64 write_playlist_segment(u64 seg_num, u64 timeref){

if (playlistFile.is_open()){
playlistFile << playlistStream.str();
}
playlistFile.close();
seg_num++;
return seg_num;
}示例7: cleanup
void cleanup() {
featureVector.clear();
os.clear(); os.seekp(0); // reset string stream
os.str("");
