How about funchook if the platform is Linux x86 or x86_64? See 'Basic API Hooking' and 'Trampoline' sections in this document to know what funchook does.
- Get all mapped ELF headers (i.e. that start with "\x7fELF") in /proc/self/maps
How about dl_iterate_phdr?

Regarding funchook, it looks like this does have a more succinct API. I'll see if that's it applicable to my use case.
FYI. When SELinux on Linux is enabled, it may prevent funchook becase it disallow modifying read-only memory for functions.
