FIFO

[Frank Buss <fb@frank-buss.de>]

I need a FIFO with a fixed size, for buffering serial data on an 
embedded system. The FIFO will be filled in an interrupt and read from 
the main function.

I guess I could implement this myself, using a simple array of e.g. 256 
bytes, and then a read index and a write index. If I specify it with 
"pragma Volatile", nothing bad should happen.

But I read about bounded vectors. Could I use this as well and save a 
few lines of code and testing work? I'm a bit worried about if the 
behavior is standardized, such that e.g. Delete_First doesn't physically 
move all elements, because this would be bad when writing it at the same 
time from the interrupt. Because it is bounded, it could be implemented 
as the simple ringbuffer as I would implement it.
