emberAfPluginFileDescriptorDispatchBadFileDescriptorCallback#
void emberAfPluginFileDescriptorDispatchBadFileDescriptorCallback (int fd)
Bad file descriptor.
Parameters
| N/A | fd | The bad file descriptor Ver.: always |
The indicated file descriptor has been detected to be bad. For example, the file descriptor caused an EBADF error on a select() call. The file descriptor will be omitted from subsequent file descriptor polling. The application responsible for the file descriptor should take steps to recover and clean up.
