"File" and "File.get<...>"
Hi to all!

Please can you help me with the following:

If i create File (to send it for example from server to client) and want to write into it Int, i use f.writeMem().putInt() or f.writeMem().putUInt(), but if i need something more than 2^32 as unsigned long long int how can i put 8-Byte integer and read it from file correctly?

Enum ClientServerCommands
{
IWantInt,
};
f.writeMem().putbyte(IWantInt).putInt(Int);

and recieving code,

Int Myint;
Myint=f.getInt();

Man, it's always that semicolon...

That's great, but Int is 4-Byte integer and i need to put and to get 8-Byte integer

Code:
//Put
File f; f.writeMem();
U64 put = 1234;
f.put((CPtr)&put, sizeof(put));

//Get
U64 get = 0;
f.pos(0);
f.get((Ptr)&get, sizeof(get));

Wouldn't
Code:
f<<put;
consume the same size? I just like to keep it simpler if its available.

As i understand, to simplify the process we can add to File.h the following

File& putU64 (U64 u64) {T<<u64; return T;} U64 getU64 () {U64 u64; T>>u64; return u64;} // write/read Unsigned LONG LONG

and you'll be able to access it by writing f.putU64() and f.getU64() (i checked, it works)

BUT there is HUGE "BUT" and it is ... if we are able to edit Esenthel's header files smile

this particular editing of a header will not cause any issue,
but generally you should never do it, as it may cause many issues sometimes impossible to debug.
as aceio pointed out, easy way is to use for File f; U64 u; code: f<<u;
