inet_ntoa

  • Article

This function converts an (Ipv4) Internet network address into a string in Internet standard dotted format.

char FAR* inet_ntoa(
  struct in_addr in
);

Parameters

  • in
    [in] Structure that represents an Internet host address.

Return Values

If no error occurs, this function returns a character pointer to a static buffer containing the text address in standard "." notation. If an error occurs, it returns NULL.

Remarks

This function takes an Internet address structure specified by the in parameter and returns an ASCII string representing the address in "." (dot) notation as in "a.b.c.d". The string returned by this function resides in memory that is allocated by Windows Sockets. The application should not make any assumptions about the way in which the memory is allocated. The data is guaranteed to be valid until the next Windows Sockets function call within the same thread, but no longer. Therefore, the data should be copied before another Windows Sockets call is made.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winsock2.h.
Link Library: Ws2.lib.
