mysql_init() - mysql/mysql.h
Allocates or initializes a MYSQL object
suitable for
mysql_real_connect(). If
mysql is a NULL pointer,
the function allocates, initializes, and returns a new object.
Otherwise, the object is initialized and the address of the
object is returned. If
mysql_init() allocates a new
object, it is freed when
mysql_close() is called to close
the connection.MYSQLmysql_real_connect()mysql_real_connect()mysqlNULLmysql_init()mysql_init()mysql_close()mysql_close()In a nonmulti-threaded environment,
mysql_init() invokes
mysql_library_init()
automatically as necessary. However,
mysql_library_init() is not
thread-safe in a multi-threaded environment, and thus neither is
mysql_init(). Before calling
mysql_init(), either call
mysql_library_init() prior to
spawning any threads, or use a mutex to protect the
mysql_library_init() call. This
should be done prior to any other client library call.mysql_init()mysql_init()mysql_library_init()mysql_library_init()mysql_library_init()mysql_library_init()mysql_init()mysql_init()mysql_init()mysql_init()mysql_library_init()mysql_library_init()mysql_library_init()mysql_library_init()
