== Description

Atomically transfer any characters buffered by the specified `syncBuf` object to the wrapped stream buffer, so that it appears in the output stream as a contiguous sequence of characters&period; The wrapped stream buffer is flushed if and only if a call was made to `sync` since the most recent call to `emit` or construction&period; Return `true` if `get&lowbar;wrapped() !&equals; nullptr`, and all of the characters in the associated output were successfully transferred, and the flush (if any) succeeded&semi; return `false` otherwise&period; The behavior is undefined unless `syncBuf` is not null&period;
