Typedef Documentation

typedef struct trace_profile_ trace_profile

Usage:

On any node that participates in iOAM Trace.

Step 1: Initialize this library by calling trace_init() Step 2: Setup a trace profile that contains all the parameters needed to compute cumulative: Call these functions: trace_profile_find trace_profile_create Step 2a: On initial node enable the profile to be used: trace_profile_set_active / trace_profile_get_active will return the profile Step 4: TBD trace_validate
