Subject: [9fans] awk: hex numbers? (and leak(1))
Topicbox-Message-UUID: bbad0e4a-ead1-11e9-9d60-3106f5b1d025

is there a way to use awk to sum hex values?
i.e. I want to sum values in the 3rd column of

block 0x000af9a8 0x00000040 0x0001ddf3 0x00000000
block 0x000afd88 0x00000040 0x0001ddf3 0x00000000

I have tried to make awk use an external program
to do the hex-to-dec conversion, but that was very
slow (probably due to many page faults).
(in the end I resorted to perl...)



context:

I've been fiddling with leak(1) to make it print
an overview of how much memory is allocated where,
as in:

location               total    calls
					   amount
					   allocated

src(0x0001d8f1);	// 247648	20
src(0x000067f8);	// 24256	59
src(0x0001da70);	// 15760	6
src(0x000128ac);	// 8256	1
src(0x000210f8);	// 4128	66
src(0x00014bc2);	// 3648	57
[...]
src(0x00006586);	// 64	1
src(0x00011a50);	// 64	1
src(0x000067c7);	// 64	1
src(0x0001ca32);	// 32	1
// 326544


I found it quite useful to get insight in where
the memory goes (even when it is not leaked) -
but maybe we already have this functionality
somewhere, and I missed it?
