Set the pdelay interval
#include <dcmd_ptpd.h> #define DCMD_PTPD_SET_PDELAY_INTERVAL __DIOT(_DCMD_NET, 14, MyPDelayIntervalInternal )
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 |
(QNX Neutrino 7.0 or later) This command sets the mean time interval between successive PDELAY_REQ messages in the Precision Time Protocol.
A MyPDelayIntervalInternal that's set to the base-2 logarithm of the interval, in seconds, that you want to use:
typedef uint32_t MyPDelayIntervalInternal;
None.
MyPDelayIntervalInternal my_pdelay_interval = 3; if(devctl(fd, DCMD_PTPD_SET_PDELAY_INTERVAL, &my_pdelay_interval, sizeof my_pdelay_interval, NULL) != EOK) { /* Error */ }
