仅供参考：
void HexDump(char *buf,int len,int addr) {
int i,j,k;
char binstr[80];
for (i=0;i<len;i++) {
if (0==(i%16)) {
sprintf(binstr,"%08x -",i+addr);
sprintf(binstr,"%s %02x",binstr,(unsigned char)buf[i]);
} else if (15==(i%16)) {
sprintf(binstr,"%s %02x",binstr,(unsigned char)buf[i]);
sprintf(binstr,"%s ",binstr);
for (j=i-15;j<=i;j++) {
sprintf(binstr,"%s%c",binstr,(""!""<buf[j]&&buf[j]<=""~"")?buf[j]:""."");
}
printf("%s\n",binstr);
} else {
sprintf(binstr,"%s %02x",binstr,(unsigned char)buf[i]);
}
}
if (0!=(i%16)) {
k=16-(i%16);
for (j=0;j<k;j++) {
sprintf(binstr,"%s ",binstr);
}
sprintf(binstr,"%s ",binstr);
k=16-k;
for (j=i-k;j<i;j++) {
sprintf(binstr,"%s%c",binstr,(""!""<buf[j]&&buf[j]<=""~"")?buf[j]:""."");
}
printf("%s\n",binstr);
}
}

使用1楼的代码，给个测试用例，你看看：
int main(void)
{
char buf[40] = "125a3ADC566742->->45!23afasdb2345~+asd";
HexDump(buf, strlen(buf), (int)buf);
return 0;
}
//002ffdd4 - 31 32 35 61 33 41 44 43 35 36 36 37 34 32 2d 3e 125a3ADC566742->
//002ffde4 - 2d 3e 34 35 21 32 33 61 66 61 73 64 62 32 33 34 ->45!23afasdb234
//002ffdf4 - 35 7e 2b 61 73 64 5~+ asd
