/**

This comment block contains doxygen tags, it should be a doxygen block.

Dito (even if the (other params same as above) part will make no sense in a doxygen html output).

I find it weird that the position gets changed to something out of bound even if the exception is thrown.
The behavior of the read() function seems more logical to me. Thought ?

Use types from cstdint.

@Fabien that would make for a good linter that can auto-correct.

I agree; looks like this seek() method got abandoned in a later commit anyway. (I'm gonna have to be more careful with the git blame forward-looking :-) ) https://github.com/bitcoin/bitcoin/commit/958e1a307e92f6678459ebdcd64e05b61f5f3a77#diff-eb3b977a68473a9d20093cbe90c659e6
