csx_ConvertSpeed(9F)					   Kernel Functions for Drivers 				      csx_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.
