The MySQL Library, Part 1.
The files here are for producing MySQL as a library (for
example, a Windows DLL). The idea is that, instead of producing
separate mysql (client) and
mysqld (server) programs, one produces a
library. Instead of sending messages, the client part merely
calls the server part.
The libmysql files are split into three
directories: libmysql (this one),
libmysql_r (the next one), and
libmysqld (the next one after that).
The "library of mysql" has some client-connection modules. For
example, as described in an earlier section of this manual,
there is a discussion of
libmysql/libmysql.c which sends packets
from the client to the server. Many of the entries in the
libmysql directory (and in the following
libmysqld directory) are 'symlinks' on
Linux, that is, they are in fact pointers to files in other
directories.
The program files on this directory are:
conf_to_src.c --- has to do with charsets
dll.c --- initialization of the dll library
errmsg.c --- English error messages, compare \mysys\errors.c
get_password.c --- get password
libmysql.c --- the code that implements the MySQL API, that is, the functions a client that wants to connect to MySQL will call
manager.c --- initialize/connect/fetch with MySQL manager
