To avoid memory leaks after the application is done using the library (for example, after closing the connection to the server), be sure to callmysql_library_end()explicitly. This enables memory managment to be performed to clean up and free resources used by the library....
This function finalizes the MySQL library. Call it when you are done using the library (for example, after disconnecting from the server). The action taken by the call depends on whether your application is linked to the MySQL client library or the MySQL embedded server library. For a client...
libmysqlclientlibrary by using the-lmysqlclientflag,mysql_library_end()performs some memory management to clean up. For an embedded server application linked against thelibmysqldlibrary by using the-lmysqldflag,mysql_library_end()shuts down the embedded server and then cleans up. explicitly. This ...

2.本以为这样就应该没有问题了,但是进行模拟压力测试时,发现每次连接都会产生8~16K的内存(单纯的进行mysql连接),查了一下资料,是每次调用mysql连接后除了进行mysql_close之外,还要使用mysql_library_end进行释放。(http://www.cnblogs.com/cobbliu/p/3709051.html) ...
