umad_done() finalizes the use of the umad library.

Return Value

umad_init() and umad_done() return 0 on success, and -1 on error. Error is returned from umad_init() if infiniband umad can’t be opened, or the abi version doesn’t match. There are no errors currently returned by umad_done().

Notes

If an error occurs during the library initialization, no further use of the umad library should be attempted.
