Accepts a connection on a specified socket.


#include <prio.h>

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


The function has the following parameters:

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


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.


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.
