I've got a pair of Windows sockets and I want the client to send certain variables to the server. The server should somehow tell the client which variables it shall send.
I got the idea that the server could just send the name of the desired variable and the client should somehow map this string onto one of its variables but I don't know how to do it.
Is this the right approach anyway, or do you have a better idea?
How many variables?
How many types of variables?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
It first maybe 2-4 Variables, just to test the basic programm.Originally Posted by Salem
Later up to 100.
Mostly integers maybe som chars and booleans
How about
On receipt of a string, youCode:enum varType { isInt, isChar, isDouble, }; struct varInfo { const char *name; enum varType type; void *ptr; }; int magic; double money; char gender; struct varInfo info[] = { { "magic", isInt, &magic }, { "money", isDouble, &money }, { "gender", isChar, &gender }, };
- search the array
- if it's a match, cast a pointer of the appropriate type and send the data.

Thank you for this solution.
It sounds good and I will test it.
