.SH NAME
io_uring_prep_bind \- prepare a bind request
.SH SYNOPSIS
.nf
.B #include <sys/socket.h>
.B #include <liburing.h>
.PP
.BI "void io_uring_prep_bind(struct io_uring_sqe *" sqe ","
.BI "                          int " sockfd ","
.BI "                          struct sockaddr *" addr ","

.SH DESCRIPTION
The
.BR io_uring_prep_bind (3)
function prepares a bind request. The submission queue entry
.I sqe
is setup to assign the network address at
.IR addr ,
of length
.IR addrlen ,
to the socket descriptor
.IR sockfd.

This function prepares an async
.BR bind (2)
request. See that man page for details.

.SH RETURN VALUE
None
.SH ERRORS
The CQE
.I 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
.B -1
on failure and set
.I errno
to the actual error value, io_uring never uses
.IR errno .
Instead it returns the negated
.I errno
directly in the CQE
.I res
field.
