/**

Methods for tracing from user side.

These methods are used to output trace packets.

Each trace packet consists of attributes and the user defined payload.

In order to output trace packets, tracing needs to be

included and enabled at compile time in the executable,

as well as be filtered at run-time.

Note:

OSTv2 does not enforce any security. It is the developer's responsibility

to ensure that trace packets do not contain any sensitive information that

may undermine platform security.

For more information about the attributes please @see opensystemtrace_types.h.

The attributes in @see TTraceContext are used to identify and filter the trace packet.

@see opensystemtrace.mmh
