CMAP_FD_GET(3) Corosync Cluster Engine Programmer's Manual CMAP_FD_GET(3)

NAME

cmap_fd_get - Dispatches callbacks from the CMAP service

SYNOPSIS

#include <corosync/cmap.h>


cs_error_t cmap_fd_get (cmap_handle_t handle, int *fd);

DESCRIPTION

The cmap_fd_get function is used to retrieve the file descriptor that
may be used with the poll system call to determine when
cmap_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 CMAP library.

RETURN VALUE

This call returns the CS_OK value if successful, otherwise an error
is returned.
