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