Re^2: External C function called through XS not Doing The Right Thing

? Are you sure about "V0C*", ?

You really want V An unsigned long (32-bit) in "VAX" (little-endian) order. Maybe you mean "C0" as in character mode?

I am not 100% sure, I've tried a few things. I just know that with "V0C*", I get the exact same parameters from a C program as I do with the Perl script in the called function. I'll re-review the pack documentation now that I at least have a workaround.	[reply]

After reviewing the docs, because the function accepts an `unsigned char array[8]`, I went with `pack "C[8]", ...;`, as from what I can tell, that's most appropriate. This didn't solve the initial issue, but thanks for pointing that out!	[reply] [d/l] [select]
