uint8_t	fill_index

Detailed Description

A pair of buffers, one being filled while the other is drained.

Note

fill_idx is the only member; the buffers it indexes are stored elsewhere.

fill_index is the only member. The buffers it indexes are stored elsewhere.

The two roles are one bit. The drain index is this one's complement. A swap is a flip and there is no second member to keep in step.

Warning

What holds fill_index to 0 or 1 is mmgr_pingpong_init setting it and mmgr_pingpong_swap flipping it. A pair that has not been through mmgr_pingpong_init carries whatever its storage contained, and no call here tests the value.
