A synchronous function call, identified by an _s suffix in the function name, must return before the client can continue executing code. Synchronous functions return LDAP_SUCCESS if successful or another LDAP e
Asynchronous callback指的就是caller call了callee,并不同步地等待callee返回,而是在callee完成返回时通过callback通知caller。
Strongly typed programming languages, such as Java or C#, can take advantage of having two distinctly named API calls for synchronous and asynchronous executions. The two calls can have different return types. For example, Connector/J can use execute() to return a RowResult or DocResult and ex...
Call asynchronous method from synchronous method in C# public async Task<TResult> MyMethodAsync(){Task<TResult> longRunningTask = LongRunningOperationAsync();// independent work which doesn't need the result of LongRunningOperationAsync can be done here...
That work is represented by a call to the synchronous method DoIndependentWork. DoIndependentWork is a synchronous method that does its work and returns to its caller. AccessTheWebAsync has run out of work that it can do without a result from getStringTask. AccessTheWebAsync next wants to ...

Synchronous call ofSQLSetStmtAttrandSQLSetConnectAttr SQLSetConnectAttrsupports asynchronous operations but the invocation ofSQLSetConnectAttrto set SQL_ATTR_ASYNC_DBC_EVENT is always synchronous. SQLSetStmtAttrdoes not support asynchronous execution. Error-out scenario ...
I’ve seen too many applications suffer extreme performance problems due to synchronous logging. The library should be as small as possible. I don’t want my users to have to download and load a 1 MB DLL for a feature as simple as logging. The smaller, the better. I didn’t want to...
