Kernel Functions for Driverscsx_ConvertSpeed(9F)


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.
