Internally the sysmodule uses the standard hostent struct, but using s16 for h_addrtype and h_length: | |||
struct hostent { | |||
char* h_name; | |||
char** h_aliases; | |||
s16 h_addrtype; | |||
s16 h_length; | |||
char** h_addr_list; | |||
}; | |||
However, the struct returned is different from the internal one: | |||
struct hostent_3ds_t { | |||
s16 h_addrtype; //< Host address type | |||
s16 h_length; //< Length of address. Maximum of 16 for IPV6 | |||
s16 h_addr_count; //< Number of addresses returned. Maximum of 24 | |||
s16 h_alias_count; //< Number of aliases returned. Maximum of 24 | |||
char[256] h_name; //< Official name of host | |||
char[256][24] h_aliases; //< Alias list | |||
char[16][24] h_addr_list; //< List of addresses from name server | |||
}; | |||
Its size is of 0x1A88 bytes. | |||
