== NAME


nng_str_sockaddr - get string representation of socket address

== SYNOPSIS

[source, c]
----
#include <nng/nng.h>

#define NNG_MAXADDRSTRLEN (NNG_MAXADDRLEN+16)
const char *nng_str_sockaddr(const nng_sockaddr *sa, char *buf, size_t bufsz)
----

== DESCRIPTION

The `nng_str_sockaddr()` is used to provide a displayable representation
for the socket address _sa_.
The content will be stored the location provided by _buf_, and will be
formatted to fit within _bufsz_ bytes, truncating if necessary.

As long as _bufsz_ is greater than zero, the result will be properly
zero-terminated in the usual fashion.

The `NNG_MAXADDRSTRLEN` can be used to provide a buffer large enough to hold most socket addresses.
It is possible for applications to use very much larger socket addresses (using very long paths
for IPC or inproc), but such addresses are not generally compatible with other implementations,
and will be truncated here.

== RETURN VALUES

This function returns the _buf_ argument.

== ERRORS

None.
