* Name: inet_ntoa |
|
* |
|
* Description: |
|
* The inet_ntoa() function converts the Internet host address in given in |
|
* network byte order to a string in standard numbers-and-dots notation. |
|
* The string is returned in a statically allocated buffer, which subsequent |
|
* calls will overwrite. |
