7.4.4 mysql_next_result_nonblocking()

enum net_async_status
mysql_next_result_nonblocking(MYSQL *mysql)

Description

Note

mysql_next_result_nonblocking() is an asynchronous function. It is the counterpart of the mysql_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 to mysql_next_result(). For details about the latter, see Section 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_status status indicator.

mysql_next_result_nonblocking() was added in MySQL 8.0.16.

Return Values

Returns an enum net_async_status value. See the description in Section 7.2, “C API Asynchronous Interface Data Structures”. A NET_ASYNC_COMPLETE_NO_MORE_RESULTS return status indicates there are no more results available. A NET_ASYNC_ERROR return status indicates an error.

Example

See Chapter 7, C API Asynchronous Interface.
