/*!
* \brief Main Channel structure associated with a channel.
*
* \note 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.
