Binds an address to a specified socket.

Syntax

#include <prio.h>

PRStatus PR_Bind(
  PRFileDesc *fd,
  const PRNetAddr *addr);

Parameters

The function has the following parameters:

fd

A pointer to a PRFileDesc object representing a socket.

addr

A pointer to a PRNetAddr object representing the address to which the socket will be bound.

Returns

The function returns one of the following values:

• Upon successful binding of an address to a socket, PR_SUCCESS.
• If unsuccessful, PR_FAILURE. Further information can be obtained by calling PR_GetError.

Description

When a new socket is created, it has no address bound to it. PR_Bind assigns the specified address (also known as name) to the socket. If you do not care about the exact IP address assigned to the socket, set the inet.ip field of PRNetAddr to PR_htonl(PR_INADDR_ANY). If you do not care about the TCP/UDP port assigned to the socket, set the inet.port field of PRNetAddr to 0.

Note that if PR_Connect is invoked on a socket that is not bound, it implicitly binds an arbitrary address the socket.

Call PR_GetSockName to obtain the address (name) bound to a socket.
