io\_uring\_prep\_bind - prepare a bind request

# [SYNOPSIS](#SYNOPSIS)

```
#include <sys/socket.h>
#include <liburing.h>
```

```
void io_uring_prep_bind(struct io_uring_sqe *sqe,
                          int sockfd,
                          const struct sockaddr *addr,
                          socklen_t addrlen);
```

# [DESCRIPTION](#DESCRIPTION)

The [**io\_uring\_prep\_bind**(3)](/man/os/liburing/io_uring_prep_bind.3) function prepares a bind request. The submission queue entry *sqe* is setup to assign the network address at *addr*, of length *addrlen*, to the socket descriptor *sockfd.*

This function prepares an async [**bind**(2)](/man/os/liburing/bind.2) request. See that man page for details.

# [RETURN VALUE](#RETURN_VALUE)

None

# [ERRORS](#ERRORS)

The CQE *res* field will contain the result of the operation. See the related man page for details on possible values. Note that where synchronous system calls will return **-1** on failure and set *errno* to the actual error value, io\_uring never uses *errno*. Instead it returns the negated *errno* directly in the CQE *res* field.
