std::basic_istream<CharT,Traits>::sync
From cppreference.com
| int sync(); |
||
Implementation-defined function. Depending on the implementation and on the type of the associated stream buffer, may empty the get area of rdbuf(), may fill it from the associated input sequence, may do nothing at all, or do something else.
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.

Parameters
(none)
Return value
0 on success, -1 on failure or if the stream does not support this operation (is unbuffered).
Notes
As with readsome(), it is implementation-defined whether this function does anything with standard streams.
