* Name: inet_ntoa
|
|
*
|
|
* Description:
|
|
* The inet_ntoa() function converts the Internet host address 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.
