+# nng_pair_open
+
+## NAME
+
+nng_pair_open --- create _PAIR_ socket
+
+## SYNOPSIS
+
+#### Version 0
+```c
+#include <nng/protocol/pair0/pair.h>
+
+int nng_pair0_open(nng_socket *s);
+
+int nng_pair0_open_raw(nng_socket *s);
+```
+
+#### Version 1
+```c
+#include <nng/protocol/pair1/pair.h>
+
+int nng_pair1_open(nng_socket *s);
+
+int nng_pair1_open_raw(nng_socket *s);
+
+int nng_pair1_open_poly(nng_socktet *s);
+```
+
+## DESCRIPTION
+
+The `nng_pair0_open()` and `nng_pair1_open()` functions
+create a [_PAIR_][pair] version 0 or version 1
+[socket][socket] and return it at the location pointed to by _s_.
+
+The `nng_pair0_open_raw()` and `nng_pair1_open_raw()` functions
+create a _PAIR_ version 0 or version 1 socket in
+[raw mode][raw] and return it at the location pointed to by _s_.
+
+The `nng_pair1_open_poly()` function opens a pair version 1 socket in
+{{i:polyamorous mode}}.
+
+> [!NOTE]
+> Polyamorous mode is deprecated and should not be used in new applications.
+> The `nng_pair1_open_poly()` function will likely be removed in a future release.
+
+## RETURN VALUES
+
+These functions returns 0 on success, and non-zero otherwise.
+
+## ERRORS
+
+* `NNG_ENOMEM`:: Insufficient memory is available.
+* `NNG_ENOTSUP`:: The protocol is not supported.
