PTP_SET_TIME

Set the current PTP time

Synopsis

#include <io-sock/ptp.h>

#define PTP_SET_TIME		0x103

Arguments to ioctl():


Argument	Value
fd	File descriptor obtained by opening the device
request	SIOCSDRVSPEC
Additional argument	A pointer to an `ifdrv`

Description

This command sets the current time as calculated by the PTP module.

Input

A filled-in ifdrv, defined in net/if.h.

struct ifdrv {
	char		ifd_name[IFNAMSIZ];
	unsigned long	ifd_cmd;
	size_t		ifd_len;
	void		*ifd_data;
};

Fill in each member using the following information:

ifd_name: The interface name; e.g., en0
ifd_cmd: PTP_SET_TIME
ifd_len: The size of a ptp_time structure
ifd_data: A pointer to a ptp_time structure that contains the time to set

Output

None.
