C++ uses its own header files, cstdlib in this case. So there would be no problem to provide two overloads for strtol. Other functions in cstdlib, like strchr, actually do provide two overloads for pointers to const and non-const character arrays. So, why not strtol? Heinz --- [ comp.std.c++ is moderated.
