This function is similar to simgear::strutils::to_int(), except it is:
- generic: the return type, selected with the first template
parameter, can be an arbitrary integral type. This type also defines
the set of accepted input strings ("values").
- stricter regarding the input: it must be non-empty and contain only
valid digits for the specified base (second template parameter). If
the input doesn't conform to these constraints or is too large to
fit into the specified type, an exception with a suitable error
message is raised.
- faster (12 to 17 times as fast as simgear::strutils::to_int() on my
system, depending on compilation flags): this is probably a
consequence of not using std::stringstream to do the conversion.
The function template is only instantiated for <int, 10> and
<unsigned int, 10> in order to be sure not to waste memory (see comments
in strutils.cxx). If you need it for other combinations of type and
base, just enable them by adjusting the corresponding '#if 0 / #endif'
pairs in strutils.cxx and strutils_test.cxx.
