I'm a new user in GAP and I would like to know if it's possible to call
functions written in C from GAP.
In principle it is possible to call C functions from GAP (after all the
GAP kernel is written in C).
Unfortunately it is quite difficult, because the C functions must follow
certain rules. For example, they must use GAP's storage manager
(Gasman). Also they must evaluate and check their arguments.
If you could describe what you would like to do, it would be possible to
estimate how much work this might be.
