## Detailed Description

These are the default debug channels pre-defined in libcwd.

## Variable Documentation

always_channel_ct libcwd::channels::dc::always

A special channel that is always turned on.

This channel is always on; it can not be turned off. It is not in the list of debug channels. When used with a label it will print as many '>' characters as the size of the largest real channel.

continued_channel_ct libcwd::channels::dc::continued

A special channel to continue to write a previous debug channel.

  Using continued_cf, dc::continued and dc::finish

fatal_channel_ct libcwd::channels::dc::core

The special COREDUMP channel.

channel_ct libcwd::channels::dc::debug

The DEBUG channel.

fatal_channel_ct libcwd::channels::dc::fatal

The special FATAL channel.

continued_channel_ct libcwd::channels::dc::finish

A special channel to finish writing continued debug output.

  Using continued_cf, dc::continued and dc::finish

channel_ct libcwd::channels::dc::malloc

The MALLOC channel.

Referenced by libcwd::debug_ct::push_margin(), and libcwd::debug_ct::push_marker().

channel_ct libcwd::channels::dc::notice

The NOTICE channel.

channel_ct libcwd::channels::dc::system

The SYSTEM channel.

channel_ct libcwd::channels::dc::warning
