    PR_Accept

    « NSPR API Reference « I/O Functions

    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.
