编码过程中我们有时候需要将数据的十六进制值打出来看看,这里做一下记录

#include <stdio.h>
#include <ctype.h>
#include <unistd.h>

void pretty_print(uint8_t* ret,size_t size)
{
    for (size_t i = 0; i < size; i++)
    {
        size_t c = i;
        printf("%08zx  ",i);
        for (size_t j = 0; j < 8; j++, c++)
        {
            if (c < size)
            {
                printf("%02X ", ret[c]);
            }
            else
            {
                printf("   ");
            }
        }
        printf(" ");
        for (size_t j = 0; j < 8; j++, c++)
        {
            if (c < size)
            {
                printf("%02X ", ret[c]);
            }
            else
            {
                printf("   ");
            }
        }
        c = i;
        printf("   |");
        for (size_t j = 0; j < 16 && c < size; j++, c++)
        {
            if (isprint(ret[c]) && ret[c])
            {
                printf("%c", ret[c]);
            }
            else
            {
                printf(".");
            }
        }
        i = i + c - 1;
        printf("|\n");
    }
    printf("%08zx\n",size);
}
