how to find the definitions of some functions?

[Fengwei]

Hi all:
         Thank you for attention to my question.
         I want to know that how samba parses the parameters of the smb.conf, like “read list”, “write list” and so on. In the source code of samba4.3.11,I can find the declarations of some functions, like  char **lp_read_list(int), char**lp_write_list and so on.But I can’t the definitions of these functions.so, how can I find them in the source code?
         Best regards!
