When you debugging a dynamic link library on macOS, maybe you need to list some functions (e.g. functions). Here is a useful commands you can use:
list all symbols:
sudo symbols /path/to/the/so/file
You can use grep to filter you interested thing, for example:
sudo symbols /path/to/the/so/file | grep mysql_affected_rows
Sometimes, we may need to set the arch:
sudo symbols /path/to/the/so/file -arch x86_64 | grep mysql_affected_rows
