我在下面的小代码中有这个文件名是从命令行传递的。这个程序被execlp()
另一个程序调用。我希望命令的 o/p 在system()
这里被调用到文件名中argv[2]
。不知道如何做到这一点。
#include <stdio.h>
int main(int argc,char *argv[])
{
char c;
printf("Received : %s filename: %s\n",argv[1],argv[2]);
FILE *fp=fopen(argv[2],"w");
system("./linked_list");
printf("Here...\n");
sleep(5);
//sleep(3*atoi(argv[2]));
return 0;
}
./linked_list 的 o/p 只是一个打印出来的列表,如下所示:
****printing list****
