DCMD_PTPD_SET_PDELAY_INTERVAL

Set the pdelay interval

Synopsis:

#include <dcmd_ptpd.h>

#define DCMD_PTPD_SET_PDELAY_INTERVAL	__DIOT(_DCMD_NET, 14, MyPDelayIntervalInternal )

Arguments to devctl():

Argument Value
filedes A file descriptor that you obtained by opening /dev/ptpd
dcmd DCMD_PTPD_SET_PDELAY_INTERVAL
dev_data_ptr A pointer to a MyPDelayIntervalInternal
n_bytes sizeof(MyPDelayIntervalInternal)
dev_info_ptr NULL

Description:

(QNX Neutrino 7.0 or later) This command sets the mean time interval between successive PDELAY_REQ messages in the Precision Time Protocol.

Note: In order to use this command, you must specify the -K option when you start ptpd-avb. Note that ptpd doesn't support this command.

Input:

A MyPDelayIntervalInternal that's set to the base-2 logarithm of the interval, in seconds, that you want to use:

typedef uint32_t MyPDelayIntervalInternal;

Output:

None.

Example:

MyPDelayIntervalInternal my_pdelay_interval = 3;

if(devctl(fd, DCMD_PTPD_SET_PDELAY_INTERVAL, &my_pdelay_interval,
          sizeof my_pdelay_interval, NULL) != EOK)
{
   /* Error */
}
