How can I recover binary data from the INTDATA file using the provided C structure?
For instance if you detect that the data is in big-endian format and needs to be converted to little-endian (or vice versa), you’ll have to perform byte swapping to convert a 16-bit or 32-bit value from big-endian to little-endian, using this approach 
uint16_t swap_uint16(uint16_t val) {
    return (val << 8) | (val >> 8);
}

uint32_t swap_uint32(uint32_t val) {
    return ((val << 24) & 0xFF000000) |
           ((val <<  8) & 0x00FF0000) |
           ((val >>  8) & 0x0000FF00) |
           ((val >> 24) & 0x000000FF);
}
uint16_t swap_uint16(uint16_t val) {
    return (val << 8) | (val >> 8);
}

uint32_t swap_uint32(uint32_t val) {
    return ((val << 24) & 0xFF000000) |
           ((val <<  8) & 0x00FF0000) |
           ((val >>  8) & 0x0000FF00) |
           ((val >> 24) & 0x000000FF);
}
