| int sync(); |
||
Fills the input cache buffer with data from the underlying input device.
First, constructs a sentry object with noskipws set to true. Afterwards,
if rdbuf() is a null pointer, returns -1
Otherwise, calls rdbuf()->pubsync(). If that function returns -1, calls setstate(badbit) and returns -1. Otherwise, returns 0.
