int socu_getaddrinfo(const char *node, const char *service, const struct addrinfo *hints, struct addrinfo **res, addrinfo_3ds_t *info, s32 info_count, s32 * count)
This function will store each result entry in the form of the following
structure :
struct addrinfo_3ds_t
{
s32 ai_flags;
s32 ai_family;
s32 ai_socktype;
s32 ai_protocol;
u32 ai_addrlen;
char ai_canonname[256];
struct sockaddr_storage ai_addr;
};
Its size is 0x130.
Note that the command will simply fill whatever it can, but never issue
any error if there isn’t enough memory provided to store those entries.
However, the count of entries will always hold the correct value, that
way you can reallocate memory and call the function again.
