The storage for the +network address structure is allocated by, and remains the +responsibility of, the calling client. + + +Syntax +------ + +.. code:: + + #include <prnetdb.h> + + PRStatus PR_InitializeNetAddr( + PRNetAddrValue val, + PRUint16 port, + PRNetAddr *addr); + + +Parameters +~~~~~~~~~~ + +The function has the following parameters: + +``val`` + The value to be assigned to the IP Address portion of the network + address. This must be ``PR_IpAddrNull``, ``PR_IpAddrAny``, or + ``PR_IpAddrLoopback``. +``port`` + The port number to be assigned in the network address structure. The + value is specified in host byte order. +``addr`` + A pointer to the :ref:`PRNetAddr` structure to be manipulated. + + +Returns +~~~~~~~ + +The function returns one of the following values: + +- If successful, ``PR_SUCCESS``. +- If unsuccessful, ``PR_FAILURE``. This may occur, for example, if the + value of val is not within the ranges defined by ``PRNetAddrValue``. + You can retrieve the reason for the failure by calling + :ref:`PR_GetError`. + + +Description +----------- + +:ref:`PR_InitializeNetAddr` allows the assignment of special network +address values and the port number, while also setting the state that +indicates the version of the address being used. + +The special network address values are identified by the enum +``PRNetAddrValue``: + +.. code:: + + typedef enum PRNetAddrValue{ + PR_IpAddrNull, + PR_IpAddrAny, + PR_IpAddrLoopback + } PRNetAddrValue; + +The enum has the following enumerators: + +``PR_IpAddrNull`` + Do not overwrite the IP address. This allows the caller to change the + network address' port number assignment without affecting the host + address. +``PR_IpAddrAny`` + Assign logical ``PR_INADDR_ANY`` to IP address. This wildcard value + is typically used to establish a socket on which to listen for + incoming connection requests. +``PR_IpAddrLoopback`` + Assign logical ``PR_INADDR_LOOPBACK``. A client can use this value to + connect to itself without knowing the host's network address. |
