CPU_INT32U SNTPc_GetRoundTripDly_us (SNTP_PKT *ppkt

...

SNTPc_ERR *p_err);

Arguments

ppkt                         Pointer  Pointer to the SNTP message packet to compute.

p_err               Pointer to variable that will receive the return error code from this function

Returned Values

SNTP packet round trip delay in us.

Required Configuration

Module Configuration.

Notes / Warnings

1. If the round trip delay is faster than the precision of the system clock, then the round trip delay is approximated to 0.
   
   

2. Only the integer part of the round trip delay is returned.

Example Usage

none.
