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_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.

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

       cmap_dispatch(3), cmap_overview(8)
