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.
