struct convert char viceversa
PostPosted: Mon Mar 02, 2009 3:40 am     Reply with quote
Hi,

I've a structure:
Code:

struct _alarm {
   float temp1_Temp;
   int8  temp1_dir;
   float temp2_Temp;
   int8  temp2_dir;
   float volt_volt;
   int8  volt_dir;
   float amp_amp;
   int8  amp_dir;
};
struct _alarm alarm;
char buffer[50];

If I'd like copy the struct in char buffer and viceversa in the elegant mode with use typecast

How I do?

Easiest, don't.
Just use a union.
That way the data doesn't have to move.
If you must move it, then use the memcpy function.

Best Wishes
