17 The cmap_fd_get function is used to retrieve the file descriptor that
18 may be used with the poll system call to determine when cmap_dis‐
19 patch(3) won't block. The handle argument may not be used directly
20 with poll because it is not the file descriptor, but instead an inter‐
21 nal identifier used by the CMAP library.

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