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.
