Disable structure padding in C without using pragma

Question

How can I disable structure padding in C without using pragma?

Answer 1

We can disable structure padding in c program using any one of the following methods.

-> use __attribute__((packed)) behind definition of structure. for eg.

struct node {
    char x;
    short y;
    int z;
} __attribute__((packed));

-> use -fpack-struct flag while compiling c code. for eg.

$ gcc -fpack-struct -o tmp tmp.c

Hope this helps. Thanks.
