NAME¶
evs_fd_get - Dispatches callbacks from the EVS service
SYNOPSIS¶
#include <corosync/evs.h>
int evs_fd_get(evs_handle_t handle, int *fd);
DESCRIPTION¶
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.
RETURN VALUE¶
This call returns the EVS_OK value if successful, otherwise an error is
returned.
ERRORS¶
The errors are undocumented.
