從 stdin 讀取輸入的C程式樣本 && python指令碼調用可執行檔

#include <stdio.h>#include <string.h>#include <unistd.h>#define MAX_BUFFER_LENGTH 1024*10int main(int argc, char *argv[]){    char buf[ MAX_BUFFER_LENGTH ];    int length = 0;    if( (length = read( 0, buf,  MAX_BUFFER_LENGTH )) < 0 ) {        return -1;    }    buf[length] = '\0';    printf("input: \n%s\n", buf);    return 0;}

test:

a='Hello world!'echo $a | ./a.out

也可以通過python指令碼來調用：

#!/usr/bin/pythonimport subprocessinput_data = 'Hello world!'a = subprocess.Popen('./a.out', stdin = subprocess.PIPE, stdout = subprocess.PIPE)a.stdin.write(input_data)output = a.stdout.read()print output
