-== NAME
-
-nn_errno - return most recent error (compatible API)
-
-== SYNOPSIS
-
-[source,c]
-----
-#include <nanomsg/nn.h>
-
-int nn_errno(void);
-----
-
-== DESCRIPTION
-
-The `nn_errno()` function returns the error number corresponding to the
-most recent failed operation by the calling thread.
-
-NOTE: This function is provided for API
-xref:nng_compat.3compat.adoc[compatibility] with legacy _libnanomsg_.
-Consider using the relevant xref:libnng.3.adoc[modern API] instead.
-
-IMPORTANT: The error numbers returned from this function may include
-errors caused by system functions, which overlap the usual `errno` variable,
-and this function simply returns the value of `errno`.
-However, the values returned may include numeric values that are not
-defined by the system, but are unique to _libnanomsg_, such as `EFSM`.
-
-This library implements the following error numbers, in addition to any others
-that might be set for `errno` by the underlying system:
-
-
-== RETURN VALUES
-
-This function returns the value of `errno`.
-If no operation has failed, then this will be zero.
-
-== ERRORS
-
-[horizontal]
-`EINTR`:: Operation interrupted.
-`ENOMEM`:: Insufficient memory.
-`EINVAL`:: Invalid argument.
-`EBUSY`:: Resource is busy.
-`ETIMEDOUT`:: Operation timed out.
-`ECONNREFUSED`:: Connection refused by peer.
-`EBADF`:: Invalid or closed socket.
-`EAGAIN`:: Operation would block.
-`ENOTSUP`:: Protocol or option not supported.
-`EADDRINUSE`:: Requested address is already in use.
-`EFSM`:: Protocol state incorrect.
-`EPROTO`:: Protocol error.
-`EHOSTUNREACH`:: Remote peer is unreachable.
-`EADDRNOTAVAIL`:: Requested address is not available.
-`EACCES`:: Permission denied.
-`EMSGSIZE`:: Message is too large.
-`ECONNABORTED`:: Connection attempt aborted.
-`ECONNRESET`:: Connection reset by peer.
