If you put all variables on the stack, including string variables, C
does most of the memory management. If you look at some of the
liblouisxml mudules you will notice that the various functions put
everything on the stack (dynamic variables) except for things which must
be preserved frfom one call to another or shared between different
functions, which are static. Pointers can be a hassle. It is usually
better to use subscripts and let the optimpxing compiler generate good
code. liblouis and liblouisxml use pointers mostly for reference to
structures or parameters.
Others may have different opinions on C++. I didn't find any advantage
it it for what I wanted to do.
