test12.c

这个是学习嵌入式开发的重要例子

#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <errno.h>

int main(int argc, char **argv)
{
  int return_code;

  //return_code = execl("/bin/ls", "/bin/ls", "-l", (char *) 0);
  //char *v[] = { "ls", NULL };
  //char *v[] = { "./test13", NULL };
  char *v[] = { "test13", NULL };
  //return_code = execlp("ls1", "ls1", (char *) 0);
  return_code = execv("./test13", v);

  if (return_code < 0)
  {
    fprintf(stderr, "excel() failed: %s\n", strerror(errno));
  }
  else
  {
    fprintf(stderr, "excel() successed.\n");
  }

  return 0;
}
