pskc_get_key_data_timedrift(3)

NAME
pskc_get_key_data_timedrift - API function

SYNOPSIS
#include <pskc.h>

uint32_t pskc_get_key_data_timedrift(pskc_key_t * key, int * present);

ARGUMENTS

pskc_key_t * key
    a pskc_key_t handle, from pskc_get_keypackage().

int * present
    output variable indicating whether data was provided or not.

DESCRIPTION
Get the PSKC KeyPackage Key Data TimeDrift value. This element contains the device clock drift value for time-based OTP algorithms. The integer value (positive or negative drift) that indicates the number of time intervals that a validation server has established the device clock drifted after the last successful authentication. So, for example, if the last successful authentication established a device time value of 8 intervals from a specific start date but the validation server determines the time value at 9 intervals, the server SHOULD record the drift as -1.

If present is non-NULL, it will be 0 if the field is not present or 1 if it was present.

RETURNS
an integer holding the content.
