SysGetIPAddresses() causes Invalid memory read/write. Topic is solved

[Banaanae]

When using the example

Code: Select all

addresses := SysGetIPAddresses()
msg := "IP addresses:`n"
for n, address in addresses
    msg .= address "`n"
MsgBox msg

I get this error

Using Win 11, also happens

Spoiler

Also happens in v1

No problem here - with v2 on Win11.

In v1, using the posted code gets:

Error: Call to nonexistent function.
Specifically: SysGetIPAddresses()

Line#
---> 001: addresses := SysGetIPAddresses()
002: msg := "IP addresses:
"
003: For n,address in addresses
004: msg .= address "
"
005: MsgBox,msg
006: Exit

The program will exit.

Not using a v2.1X alpha btw?

In v1, using the posted code gets:

Error: Call to nonexistent function.
Specifically: SysGetIPAddresses()

Of course, this function doesn't exist in v1; and I don't see anything related in the SysGet docs.
According to the error message, the v1 code just seems to use the line Msgbox % A_IPAddress1 or similar. Again, no problems here (IPv4 addresses behind a router).
With neither of the four built-in variables. (Compare https://www.autohotkey.com/docs/v1/Variables.htm#IPAddress)

v2 docs say explicitly "only IPv4 is supported" but could that cause "Invalid memory read/write"?!?

[lmstearn]

Could be, AHK uses Winsock.h only, in there:

#ifdef IPV6STRICT
#error WINSOCK2 required.

in_addr is for ipv4 only.
Toggled off the ethernet to test, the IP now loops back to localhost, no crash either.
Quite a rabbit hole with v6, this seems to be most accepted on SO.

I have a IPv4 address
("curl ident.me" via cmd returns an ipv4)

Also tried a vpn and that didn't work

[Banaanae]

Reread docs and made a mistake (can't edit post in review so new post)

This function only returns the IP addresses of the computer's network adapters.

Ran "ipconfig /all" via command which says there's one 192.168.X.X address under "Wireless LAN adapter Wi-Fi:"

Sorry if the reason is now obvious, networking isn't my strongsuit

A_IPAddressX and SysGetIPAddresses weren't designed to handle failure. v2.0.12 fixes this.

However, whatever condition was causing it to fail will likely still do so; you'll just get an empty array instead of a Critical Error. If you are not having issues in other software, I would suggest looking at firewall/security software, or other software related to networking.
