Accepts a new connection and receives a block of data.

Syntax

#include <prio.h>

PRInt32 PR_AcceptRead(
  PRFileDesc *listenSock,
  PRFileDesc **acceptedSock,
  PRNetAddr **peerAddr,
  void *buf,
  PRInt32 amount,
  PRIntervalTime timeout);

Parameters

The function has the following parameters:

listenSock

A pointer to a PRFileDesc object representing a socket descriptor that has been called with the PR_Listen function, also known as the rendezvous socket.

acceptedSock

A pointer to a pointer to a PRFileDesc object. On return, *acceptedSock points to the PRFileDesc object for the newly connected socket. This parameter is valid only if the function return does not indicate failure.

peerAddr

A pointer a pointer to a PRNetAddr object. On return, peerAddr points to the address of the remote socket. The PRNetAddr object that peerAddr points to will be in the buffer pointed to by buf. This parameter is valid only if the function return does not indicate failure.

buf

A pointer to a buffer to hold data sent by the peer and the peer's address. This buffer must be large enough to receive amount bytes of data and two PRNetAddr structures (thus allowing the runtime to align the addresses as needed).

amount

The number of bytes of data to receive. Does not include the size of the PRNetAddr structures. If 0, no data will be read from the peer.

timeout

The timeout interval only applies to the read portion of the operation. PR_AcceptRead blocks indefinitely until the connection is accepted; the read will time out after the timeout interval elapses.

Returns

• A positive number indicates the number of bytes read from the peer.
• The value -1 indicates a failure. The reason for the failure can be obtained by calling PR_GetError.

Description

PR_AcceptRead accepts a new connection and retrieves the newly created socket's descriptor and the connecting peer's address. Also, as its name suggests, PR_AcceptRead receives the first block of data sent by the peer.
