DCMD_PTPD_GET

Get the current time

Synopsis:

#include <dcmd_ptpd.h>

#define DCMD_PTPD_GET_TIME   __DIOF(_DCMD_NET, 15, MyTimeInternal )

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

(QNX Neutrino 7.0 or later) This command gets the current time that's maintained by the Precision Time Protocol.

Note: In order to use this command, you must specify the -K option when you start ptpd or ptpd-avb.

None.

A filled-in MyTimeInternal structure, which is defined in <dcmd_ptpd.h> as follows:

typedef struct {
        uint32_t seconds;
        uint32_t nanoseconds;
} MyTimeInternal;

MyTimeInternal curr_time;

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