CSX_CONVERTSPEED 9F "Jul 19, 1996"
NAME
csx_ConvertSpeed - convert device speeds
SYNOPSIS
#include <sys/pccard.h> int32_t csx_ConvertSpeed(convert_speed_t *cs);
INTERFACE LEVEL
illumos DDI Specific (illumos DDI)
PARAMETERS
cs
Pointer to a convert_speed_t structure.
DESCRIPTION
This function is an illumos-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
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.
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.
Invalid nS or devspeed.
Bad Attributes value.
No PCMCIA hardware installed.
CONTEXT
This function may be called from user or kernel context.
