# nng\_sockaddr\_inproc(5)

inproc socket address

## NAME

nng\_sockaddr\_inproc - inproc socket address

## SYNOPSIS

```
#include <nng/nng.h>
enum sockaddr_family {
    NNG_AF_INPROC = 1,
};
typedef struct {
    uint16_t sa_family;
    uint16_t sa_name[128];
} nng_sockaddr_inproc;
```

## DESCRIPTION

An `nng_sockaddr_inproc` is the flavor of `nng_sockaddr` used to represent addresses associated with intra-process communication using the *inproc* transport.

The following structure members are present:

`sa_family`

This field will always have the value `NNG_AF_INPROC`.

`sa_name`

This field holds an arbitrary C string, which is the name of the address. The string must be `NUL` terminated, but no other restrictions exist.

**Tip**\

In order to ensure maximum compatibility, applications should avoid hard coding the size of the `sa_name` member explicitly, but use the `sizeof` operator to determine its actual size at compile time. Furthermore, the size is guaranteed to be at least 128.
