NAME
csx_ConvertSpeed - convert device speeds
SYNOPSIS

#include <sys/pccard.h> 



int32_t csx_ConvertSpeed(convert_speed_t *cs);
INTERFACE LEVEL

Solaris DDI Specific (Solaris DDI)

PARAMETERS

cs

Pointer to a convert_speed_t structure.

DESCRIPTION

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

STRUCTURE MEMBERS

The structure members of convert_speed_t are:

uint32_t Attributes;
uint32_t nS;
uint32_t devspeed;

The fields are defined as follows:

Attributes

This is a bit-mapped field that identifies the type of speed conversion to be performed. The field is defined as follows:

CONVERT_NS_TO_DEVSPEED

Converts nS to devspeed format

CONVERT_DEVSPEED_TO_NS

Converts devspeed format to nS

nS

If CONVERT_NS_TO_DEVSPEED is set, the value in the nS field is converted to a devspeed format and returned in the devspeed field.

devspeed

If CONVERT_DEVSPEED_TO_NS is set, the value in the devspeed field is converted to an nS value and returned in the nS field.

RETURN VALUES

CS_SUCCESS

Successful operation.

CS_BAD_SPEED

Invalid nS or devspeed.

CS_BAD_ATTRIBUTE

Bad Attributes value.

CS_UNSUPPORTED_FUNCTION

No PCMCIA hardware installed.

CONTEXT

This function may be called from user or kernel context.
