14 The cpg_fd_get function is used to retrieve the file descriptor that
15 may be used with the poll system call to determine when cpg_dispatch(3)
16 won't block. The handle argument may not be used directly with poll
17 because it is not the file descriptor, but instead an internal identiā
18 fier used by the CPG library.
19
21 This call returns the CS_OK value if successful, otherwise an error is
22 returned.
23
25 The errors are undocumented.
