Multithreaded programming with libmysql

481 views Asked by At

I'm using libmysql in a simple multithreaded app which will run on a uni-core embedded system processor. I read here that the client library is almost thread-safe.

Do I need to serialise my app (say, with a mutex)?

Depends on what you're doing. In a simple scenario you'd just link against libmysqlclient_r and make sure you don't share a connection with multiple threads nor execute multiple queries "simultaneously" on a single connection.

Other requirements:

  1. Before creating any threads, call mysql_library_init() to initialise the MySQL library;
  2. On each thread call mysql_thread_init() to initialise thread-specific variables before using any MySQL related functions;
  3. Before destroying a thread, call mysql_thread_end().

If your program is respecting these limitations, MySQL is your friend.
