evs_fd_get − Dispatches callbacks from the EVS service |
#include <corosync/evs.h> int evs_fd_get(evs_handle_t handle, int *fd); |
The evs_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when evs_dispatch(3) won’t block. The handle argument may not be used directly with poll because it is not the file descriptor, but instead an internal identifier used by the EVS library. |
This call returns the EVS_OK value if successful, otherwise an error is returned. |
The errors are undocumented. |
