Re: Measurement of physical memory

If you want to know the length in bytes of that message, you can use length($message), but this is only vaguely related to how much memory the string takes up.

Note, BTW, that with the Wonderful World of utf8, the number of characters in $message and it's size in bytes are not neccessarly the same. The above normaly gives the length in characters; to get the length in bytes, `use bytes (); ... $sizeof=bytes::length($message);` [download] But remember that doesn't count all the overhead of a scalar. (28 bytes on most boxes, IIRC, but there are very few circumstances where you should care.) Confession: It does an Immortal Body good. Update: Fixed tpyos.	[reply] [d/l]
