get_memory_usage_information
I have a script that is trying to get the memory used on the boxed. I am useing get_memory_usage_information I can get total memroy with out a problem just haveing a problem getting used_memory. From the SDK it looks like I can ask for used_memory just like total_memory but all I get back is zero. Any ideas? Thanks

- Hunter, can you post your code where you are having a problem. What are the values of the low and high compontents of the UInt64 structure returned?
-Joe - I'd be careful about dropping the high 32 bits of those values. For memory it's probably OK as long as you don't have more than 4GB. A safer approach would be to build a native 64 bit value from the low and high components of our UInt64 structure.
my $total_memory = &build64($memory_info->{"total_memory"}); ---------------------------------------------------------------------------- build64 ---------------------------------------------------------------------------- sub build64() { ($UInt64) = (@_); $low = $UInt64->{"low"}; $high = $UInt64->{"high"}; For some reason this doesn't work... $value64 = Math::BigInt->new($high)->blsft(32)->bxor($low); $value64 = Math::BigInt->new(Math::BigInt->new($high)->blsft(32))->bxor($low); return $value64; }
I guess that's assuming you don't have 64bit support builtin (which isn't the default) and you have the Math::BigInt module on your system.
-Joe - One last question is the get_memory_usage_information used memory the total memory used in the box, or just what is used by the TMM? Thanks
