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_dis-
patch(3) won't block. The handle argument may not be used directly with poll because it is not the file descriptor, but instead an inter-
nal identifier used by the CMAP library.
RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.
