C: Assigning structures

Name: Anonymous 2010-07-24 2:09

suppose we have the following type:

typedef struct {
    int bar;
    int baz;
    int foo;
} Something;


In order to do a copy, I usually do something like:

Something a, b;
...
memcpy ((void *) &a, (const void *) &b, sizeof(Something));

But also the following is legal (and far more quick to write).

Something a, b;
...
a = b;

Is there any disadvantage in doing the second one?

Don't write it that way.  Write it this way:

memcpy(&a, &b, sizeof(a));

These days, "memcpy" and "=" will give you the same damn assembly, except "=" is much less prone to typos.
