If I try with "errno" instead, I get raw : ~ $ ./dltest Handle: 0x2805e000, errno: 0x280f5cd4 Handle: 0x0, errno: 0x0 raw : ~ $ --- according to the manpage for dlsym(), passing 0 for handle should have the same effect as passing 0 as the path to dlopen; i.e, to access the symbol table for the running program. -- Raymond Wiker To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
