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

: 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

: 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.
