How to Get A Function Name From a Library and Address in Linux C -

-

i learning how use functions dlopen, dlsym, etc. address of given function within given library, how do opposite? example, if know process @ gtk_main+0xa7 in libgtk-x11-2.0.so.0, how can determine function is?

thanks in advance!

if know address related object space can use nm. on own libgtk-x11… gives:

# nm -d /usr/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0.2400.23 000000000006da20 t gtk_about_dialog_get_artists 000000000006d800 t gtk_about_dialog_get_authors 000000000006d260 t gtk_about_dialog_get_comments …

option -d needed dynamic symbols, , should have "t" symbols (which "really" inside object). of course these addresses related object, not address space in program.

note starting addresses of entries, if address inside function should have compute nearest address. @ nm manpage other data available.

you may find objects mapped given program looking @ /proc/pid/maps, @ least.

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
