listenerlist * | getReadyList () |
void | removeFileDescriptor (filedescriptor *fd) |
void | removeAllFileDescriptors () |
void | retryInterruptedWaits () |
void | dontRetryInterruptedWaits () |
The listener class listens for activity on a pool of filedescriptors or children of the filedescriptor class.
listener::listener | ( | ) |
Creates an instance of the listener class.
virtual listener::~listener | ( | ) | [virtual] |
Deletes this instance of the listener class.
void listener::addFileDescriptor | ( | filedescriptor * | fd | ) |
Adds the specified file descriptor to the pool that the listener is listening on.
void listener::dontRetryInterruptedWaits | ( | ) |
Causes waits not to automatically retry if interrupted by a signal. The default is to retry automatically.
listenerlist* listener::getReadyList | ( | ) |
Returns the list of file descriptors that were ready for read after the last call to waitForNonBlockingRead() or ready for write after the last call to waitForNonBlockingWrite().
void listener::removeAllFileDescriptors | ( | ) |
Removes all file descriptors from the pool.
void listener::removeFileDescriptor | ( | filedescriptor * | fd | ) |
Removes the specified file descriptor from the pool.
void listener::retryInterruptedWaits | ( | ) |
Causes waits to automatically retry if interrupted by a signal. This is the default.
int32_t listener::waitForNonBlockingRead | ( | long | sec, |
long | usec | ||
) |
Causes the application to wait until a read() will proceed without blocking or until "sec" seconds and "usec" microseconds have elapsed.
Entering -1 for either parameter causes the method to wait indefinitely.
Entering 0 for both parameters causes the method to fall through immediately, returning RESULT_TIMEOUT unless a read() will immediately proceed without blocking.
Returns RESULT_ERROR on error, RESULT_TIMEOUT on timeout and otherwise returns the number of file descriptors that are ready to be read from.
int32_t listener::waitForNonBlockingWrite | ( | long | sec, |
long | usec | ||
) |
Causes the application to wait until a write() will proceed without blocking or until "sec" seconds and "usec" microseconds have elapsed.
Entering -1 for either parameter causes the method to wait indefinitely.
Entering 0 for both parameters causes the method to fall through immediately, returning RESULT_TIMEOUT unless a write() will immediately proceed without blocking.
Returns RESULT_ERROR on error, RESULT_TIMEOUT on timeout and otherwise returns the number of file descriptors that are ready to be written to.
