PR_Accept

Accepts a connection on a specified socket.

Syntax

#include <prio.h> 

PRFileDesc* PR_Accept(
  PRFileDesc *fd, 
  PRNetAddr *addr, 
  PRIntervalTime timeout);

Parameters

The function has the following parameters:

fd
A pointer to a PRFileDesc object representing the rendezvous socket on which the caller is willing to accept new connections.
addr
A pointer to a structure of type PRNetAddr. On output, this structure contains the address of the connecting entity.
timeout
A value of type PRIntervalTime specifying the time limit for completion of the accept operation.

Returns

The function returns one of the following values:

  • Upon successful acceptance of a connection, a pointer to a new PRFileDesc structure representing the newly accepted connection.
  • If unsuccessful, NULL. Further information can be obtained by calling PR_GetError.

Description

The socket fd is a rendezvous socket that has been bound to an address with PR_Bind and is listening for connections after a call to PR_Listen. PR_Accept accepts the first connection from the queue of pending connections and creates a new socket for the newly accepted connection. The rendezvous socket can still be used to accept more connections.

If the addr parameter is not NULL, PR_Accept stores the address of the connecting entity in the PRNetAddr object pointed to by addr.

PR_Accept blocks the calling thread until either a new connection is successfully accepted or an error occurs. If the timeout parameter is not PR_INTERVAL_NO_TIMEOUT and no pending connection can be accepted before the time limit, PR_Accept returns NULL with the error code PR_IO_TIMEOUT_ERROR.
