Detailed Description

Main Channel structure associated with a channel.

Note:
XXX It is important to remember to increment .cleancount each time this structure is changed. XXX

When adding fields to this structure, it is important to add the field 'in position' with like-aligned fields, so as to keep the compiler from having to add padding to align fields. The structure's fields are sorted in this order: pointers, structures, long, int/enum, short, char. This is especially important on 64-bit architectures, where mixing 4-byte and 8-byte fields causes 4 bytes of padding to be added before many 8-byte fields.
