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 for-
     mat 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.
