mysql_next_result_nonblocking(MYSQL *mysql)Description
Note
mysql_next_result_nonblocking() is an asynchronous function. It is the counterpart of themysql_next_result() synchronous function, for use by applications that require asynchronous communication with the server. For general information about writing asynchronous C API applications, see Chapter 7, C API Asynchronous Interface.
mysql_next_result_nonblocking() is used similarly tomysql_next_result(). For details about the latter, seeSection 5.4.51, “mysql_next_result()”. The two functions differ as follows:
- mysql_next_result() returns an integer status indicator.
- mysql_next_result_nonblocking() returns an
enum net_async_statusstatus indicator.
mysql_next_result_nonblocking() was added in MySQL 8.0.16.
Return Values
Returns an enum net_async_status value. See the description inSection 7.2, “C API Asynchronous Interface Data Structures”. ANET_ASYNC_COMPLETE_NO_MORE_RESULTS return status indicates there are no more results available. ANET_ASYNC_ERROR return status indicates an error.
