打印内存的c语言实现

有很多时候，特别是linux服务端开发程序是，需要看内存块的信息，网上搜到的一个现成的代码，用了不错，记一下！

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);}}int main(void){char buf[40] = "125a3ADC566742->->45!23afasdb2345~+asd";HexDump(buf, strlen(buf), (int)buf);return 0;}
