Functions | |
int | wait_any (request_ptr req_array[], int count) |
Collection of functions to track statuses of a number of requests. | |
void | wait_all (request_ptr req_array[], int count) |
Suspends calling thread until all requests are completed. | |
bool | poll_any (request_ptr req_array[], int count, int &index) |
Polls requests. |
Group of classes which enable abstraction from operating system calls and support system-independent interfaces for asynchronous I/O.
bool poll_any | ( | request_ptr | req_array[], | |
int | count, | |||
int & | index | |||
) | [inline] |
Polls requests.
req_array | array of request_ptr objects | |
count | size of req_array | |
index | contains index of the first completed request if any |
true
if any of requests is completed, then index contains valid value, otherwise false
void wait_all | ( | request_ptr | req_array[], | |
int | count | |||
) | [inline] |
Suspends calling thread until all requests are completed.
req_array | array of request_ptr objects | |
count | size of req_array |
