Subject: ld --wrap and zcat
Date: Tue, 25 Aug 2009 00:15:00 -0000 [thread overview]
Message-ID: <4A931CE1.8090307@bcgsc.ca> (raw)
fstream::open in libstdc++ calls fopen in libc. I'd like to use ld
--wrap to hook the fopen call to call popen to decompress a .gz file
using zcat. Is this possible with ld --wrap? From my experimentation,
it seems not. Is this possible using LD_PRELOAD and dlsym?
Thanks,
Shaun
