where can i find info on sigcontext = structure on=20 linux/ia-64 ? specifically which registers hold the faulting = address/type on a=20 segmention fault and the trap no on a SIGTRAP ?

thanks

chetan

There is no 1-to-1 correspondence, but such info is stored in siginfo on ia64. See siginfo.h. --david
