csx_ConvertSize(9F)

Name

csx_ConvertSize - convert device sizes

Synopsis

#include <sys/pccard.h> 

int32_t csx_ConvertSize(convert_size_t *cs);

Interface Level

Solaris DDI Specific (Solaris DDI)

Parameters

cs

Pointer to a convert_size_t structure.

Description

csx_ConvertSize() is a Solaris-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.

Structure Members

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.

Return Values

CS_SUCCESS

Successful operation.

CS_BAD_SIZE

Invalid bytes or devsize.

CS_UNSUPPORTED_FUNCTION

No PCMCIA hardware installed.

Context

This function may be called from user or kernel context.
