一个mips虚拟机非常好代码,使用C++来编写的,希望大家多学学,

#include <sys/types.h>
#include <sys/stat.h>
#include <assert.h>
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>

#define max_size (2*1024*1024)
char buf[max_size];

int main(
    int argc,
    char* argv[])
{
    int in, out, rc;
    ssize_t n, m;

    assert(argc == 3);

    in = open(argv[1], O_RDONLY);
    assert(in >= 0);

    out = creat(argv[2], 0644);
    assert(out >= 0);

    rc = lseek(in, 0xBFC00000UL, SEEK_SET);
    assert(rc == 0xBFC00000);

    n = read(in, buf, max_size);
    assert(n >= 0);

//    m = write(out, buf, n);
//    assert(m == n);

//    fprintf(stderr, "%d bytes written to %s\n", (int)m, argv[2]);

    return 0;
