cs
Pointer to a convert_size_t structure.
csx_ConvertSize() is an illumos-specific extension that provides a
method for clients to convert from one type of device size
representation to another, that is, from devsize format to bytes and
vice versa.
The structure members of convert_size_t are:
uint32_t Attributes;
uint32_t bytes;
uint32_t devsize;
The fields are defined as follows:
Attributes
This is a bit-mapped field that identifies the type of
size conversion to be performed. The field is defined
as follows:
CONVERT_BYTES_TO_DEVSIZE
Converts bytes to devsize
format.
CONVERT_DEVSIZE_TO_BYTES
Converts devsize format to
bytes.
bytes
If CONVERT_BYTES_TO_DEVSIZE is set, the value in the
bytes field is converted to a devsize format and
returned in the devsize field.
devsize
If CONVERT_DEVSIZE_TO_BYTES is set, the value in the
devsize field is converted to a bytes value and
returned in the bytes field.
CS_SUCCESS
Successful operation.
CS_BAD_SIZE
Invalid bytes or devsize.
CS_UNSUPPORTED_FUNCTION
No PCMCIA hardware installed.
This function may be called from user or kernel context.
