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

       cmap_fd_get - Dispatches callbacks from the CMAP service

       #include <corosync/cmap.h>

       cs_error_t cmap_fd_get (cmap_handle_t handle, int *fd);

       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.

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