/* [out] */ arm_timestamp_t *timestamp
);
General description
Use arm_get_timestamp()
to obtain the current time. If the application wants to pass the arrival
time sub-buffer to arm_start_transaction(), it must call arm_get_timestamp()
to capture the arrival time in a format that is compatible with the
arrival time sub-buffer.
- timestamp
- Area where the current time is returned. The format of the timestamp
is implementation-dependent.
Returned value
On success, arm_get_timestamp
returns ARM_RC_SUCCESS. On failure, the errno and return code are
set to indicate the error. See
