void printstring(char *str)has a C++ symbolic representation something like__1cLprintstring6Fpc_v_. As no tool exists that can determine a symbol's mangled name other than the compilers themselves, trying to establish definitions of this sort within a mapfile, is not a simple task. ...
MessagePack for C# IntKey is the fastest. StringKey is slower than IntKey because matching the character string of property names is required. IntKey works by reading the array length, then for (array length) { binary decode }. StringKey works by reading map length, for (map length) { ...
