[#Sock-Accept]
= xref:Sock.adoc[Sock]::Accept
:relfileprefix: ../
:mrdocs:

accept(2) wrapper. Equivalent to `std::make_unique<Sock>(accept(m_socket, addr, addr_len))`. Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation. The returned unique_ptr is empty if `accept()` failed in which case errno will be set.

== Synopsis

Declared in `<util/sock.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
[[nodiscard]]
virtual
std::unique_ptr<Sock>
Accept(
    sockaddr* addr,
    socklen_t* addr_len) const;
----

== Return Value

A `Sock` wrapping the accepted connection, or an empty unique_ptr on error.

[NOTE]
====
The return value https://en.cppreference.com/cpp/language/attributes/nodiscard[should not be discarded^].
