* Name: gethostbyname
*
* Description:
* The gethostbyname() function returns a structure of type hostent for
* the given host name. Here name is either a hostname, or an IPv4 address
* in standard dot notation (as for inet_addr(3)), or an IPv6 address in
* colon (and possibly dot) notation.
*
* If name is an IPv4 or IPv6 address, no lookup is performed and
* gethostbyname_r() simply copies name into the h_name field
* and its struct in_addr equivalent into the h_addr_list[0] field of the
* returned hostent structure.
*
* Input Parameters:
* name - The name of the host to find.
*
* Returned Value:
* Upon successful completion, this function will return a pointer to a
* hostent structure if the requested entry was found, and a null pointer
* if the end of the database was reached or the requested entry was not
* found.
*
* Upon unsuccessful completion, gethostbyname() will set h_errno to
* indicate the error
*
