## Detailed Description

Header prepended to each ISDN4BSD kernel trace buffer entry describing a captured channel frame.

## Member Data Documentation

## ◆ count

uint32_t i4b_trace_hdr_t::count

Running frame count for this controller unit and channel type.

## ◆ dir

int32_t i4b_trace_hdr_t::dir

Transmission direction; one of the FROM_* values below.

## ◆ length

uint32_t i4b_trace_hdr_t::length

Length in bytes of the trace data (mbuf payload) that follows this header.

## ◆ trunc

uint32_t i4b_trace_hdr_t::trunc

Number of bytes truncated when the frame exceeded MCLBYTES.

## ◆ ts_sec

uint32_t i4b_trace_hdr_t::ts_sec

Timestamp seconds component at the time of capture.

## ◆ ts_usec

uint32_t i4b_trace_hdr_t::ts_usec

Timestamp microseconds component at the time of capture.

## ◆ type

uint32_t i4b_trace_hdr_t::type

Channel type from which this frame was captured; one of the TRC_CH_* values below.

## ◆ unit

uint32_t i4b_trace_hdr_t::unit

ISDN controller unit number that captured this frame.
