DESCRIPTION

24       This  function  is  a Solaris-specific extension that provides a method
25       for clients to convert from one type of device speed representation  to
26       another, that is, from devspeed format to nS and vice versa.
27

STRUCTURE MEMBERS

29       The structure members of convert_speed_t are:
30
31         uint32_t     Attributes;
32         uint32_t     nS;
33         uint32_t     devspeed;
34
35
36
37       The fields are defined as follows:
38
39       Attributes     This  is  a bit-mapped field that identifies the type of
40                      speed conversion to be performed. The field  is  defined
41                      as follows:
42
43                      CONVERT_NS_TO_DEVSPEED    Converts nS to devspeed format
44
45
46                      CONVERT_DEVSPEED_TO_NS    Converts devspeed format to nS
47
48
49
50       nS             If  CONVERT_NS_TO_DEVSPEED  is  set, the value in the nS
51                      field is converted to a devspeed format and returned  in
52                      the devspeed field.
53
54
55       devspeed       If  CONVERT_DEVSPEED_TO_NS  is  set,  the  value  in the
56                      devspeed field is converted to an nS value and  returned
57                      in the nS field.

RETURN VALUES

61       CS_SUCCESS                  Successful operation.
62
63
64       CS_BAD_SPEED                Invalid nS or devspeed.
65
66
67       CS_BAD_ATTRIBUTE            Bad Attributes value.
