#pragma pack in c code example

Example 1: #pragma pack(1) in c

#include <stdio.h>

struct a {
    char one;
    char two[2];
    char eight[8];
    char four[4];
};

struct b { 
    char one;
    short two;
    long int eight;
    int four;
};

int main(int argc, char** argv) {
    struct a twoa[2] = {}; 
    struct b twob[2] = {}; 
    printf("sizeof(struct a): %i, sizeof(struct b): %i\n", sizeof(struct a), sizeof(struct b));
    printf("sizeof(twoa): %i, sizeof(twob): %i\n", sizeof(twoa), sizeof(twob));
}

Example 2: #pragma pack(1) in c

adds  r31 = r32, 4
adds  r30 = r32  8 ;;
ld4   r31 = [r31]
ld4   r30 = [r30] ;;












add   r31 = r30, r31 ;;
st4   [r32] = r31
