| Name| Description
| xref:BloombergLP/bslstl/SyncBufBaseUtil/emitInternal.adoc[`emitInternal`] 
| 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. 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. Return `true` if `get_wrapped() != nullptr`, and all of the characters in the associated output were successfully transferred, and the flush (if any) succeeded; return `false` otherwise. The behavior is undefined unless `syncBuf` is not null.
| xref:BloombergLP/bslstl/SyncBufBaseUtil/setEmitOnSync.adoc[`setEmitOnSync`] 
| Set the "emit‐on‐sync" property of the synchronized buffer to the specified `value`. If "emit‐on‐sync" is `true`, the synchronized buffer will emit (see `emitInternal`) its buffered contents on a call to `sync` (or `pubsync`); otherwise the synchronized buffer will not be emitted on a `sync`. The behavior is undefined unless `syncBuf` is not null.
