DESCRIPTION

24       csx_ConvertSize()  is  a  Solaris-specific  extension  that  provides a
25       method for clients to convert from one type of device size  representa‐
26       tion to another, that is, from devsize format to bytes and vice versa.
27

STRUCTURE MEMBERS

29       The structure members of convert_size_t are:
30
31         uint32_t    Attributes;
32         uint32_t    bytes;
33         uint32_t    devsize;
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                      size conversion to be performed. The field is defined as
41                      follows:
42
43                      CONVERT_BYTES_TO_DEVSIZE    Converts  bytes  to  devsize
44                                                  format.
45
46
47                      CONVERT_DEVSIZE_TO_BYTES    Converts devsize  format  to
48                                                  bytes.
49
50
51
52       bytes          If  CONVERT_BYTES_TO_DEVSIZE  is  set,  the value in the
53                      bytes  field  is  converted  to  a  devsize  format  and
54                      returned in the devsize field.
55
56
57       devsize        If  CONVERT_DEVSIZE_TO_BYTES  is  set,  the value in the
58                      devsize field is converted to a bytes value and returned
59                      in the bytes field.

RETURN VALUES

63       CS_SUCCESS                  Successful operation.
64
65
66       CS_BAD_SIZE                 Invalid bytes or devsize.
