Subject: is dl_iterate_phdr() supposed to be async-signal safe?
Date: Thu, 01 Apr 2004 07:50:00 -0000 [thread overview]
Message-ID: <16491.51649.225477.81600@napali.hpl.hp.com> (raw)
Subject pretty much says it all: I thought it was meant to be
async-signal safe but looking at the __pthread_mutex_lock() code, it
pretty clearly can't be, since it's updating the count and ownership
members non-atomically with respect to signal-delivery. Or am I
missing something?
So much for dl_iterate_phdr() being an "obvious" interface... ;-/
