:relfileprefix: ../../
:mrdocs:

Consider adding this tx hash to txrequest. Should be called whenever a new inv has been received. Also called internally when a transaction is missing parents so that we can request them.

== Synopsis

Declared in `<node/txdownloadman_impl.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]

bool
AddTxAnnouncement(
    xref:NodeId-08.adoc[NodeId] peer,
    xref:GenTxid.adoc[GenTxid] const& gtxid,
    std::chrono::microseconds now);
----

== Return Value

True if the inv was dropped because we already have the tx, false otherwise.
