conversion trouble

[Zen]

Hi all.

I am having some trouble converting a function (inet_addr to be specific). The function is declared in the platform SDK as...

Code Select Expand


unsigned long inet_addr(
  const char* cp
);


i have tried the following...

Code Select Expand


declare import,inet_addr(byte *cp),unsigned int64;


and...

Code Select Expand


declare import,inet_addr(string *cp),unsigned int64;


non of my above are working, at least i dont think they are as i am getting the 10049 winsock error which means the address is not correctly formated, the nature of the above function is to do the correct formatting

If anyone can solve this little problem that would be great.

Lewis,
I haven't even fired up the Aurora demo yet but my guess (for a thousand points) would be....

Code Select Expand

declare import,inet_addr(string cp),unsigned int;

yeh i tried it without the pointer and without the long, just the int. something is going wrong somewhere but i dont know where. i am prety sure it is this function call that is doing it. The trouble is i dont know how and IP address is meant to look after it has been processed.

Okay here's something to test against.

Given an IP address string of "192.168.1.1" inet_addr will return 16885952 or in other words:
ret = inet_addr("192.168.1.1")
ret would equal 16885952

oh great thanks earn. Now i can at least check if its giving back the right IP.

A long isn't an int64, it's an int. It's kind of confusing, but in C an integer is based on the processors bits, I think. Then you have char(, short(16), long(32), long long(64, I think).

Yes i got confused when i looked through the SDK at the data types. I saw long and somehow (because i was tired) came to think it was int64 instead of plain old int.
