mysql_free_result_nonblocking(MYSQL_RES *result)Description
Note
mysql_free_result_nonblocking() is an asynchronous function. It is the counterpart of themysql_free_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_free_result_nonblocking() is used similarly tomysql_free_result(). For details about the latter, seeSection 5.4.26, “mysql_free_result()”. The two functions differ as follows:
- mysql_free_result() does not return a value.
- mysql_free_result_nonblocking() returns an
enum net_async_statusstatus indicator.
mysql_free_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_ERROR return status indicates an error.
