MySQL 5.6 C API Developer Guide
my_bool mysql_thread_init(void)
This function must be called early within each created thread
to initialize thread-specific variables. However, it may be
unnecessarily to invoke it explicitly. Calling
mysql_thread_init()
is
automatically handled
my_init()
, which itself is
called by mysql_init()
,
mysql_library_init()
,
mysql_server_init()
, and
mysql_connect()
. If you invoke
any of those functions,
mysql_thread_init()
is called
for you.
