脚本开发-从文件读取数据并参数化

直接上代码：

 

 

 

char* testfn()

{

    int count, total = 0;

    //char buffer[1000];

    char * buffer = NULL;

    int filelenth = 0;

    long file_stream;

    char * filename = "d:\\test.txt";

 

    if ((file_stream = fopen(filename, "r")) == NULL )

    {

        lr_error_message ("Cannot open %s", filename);

        return NULL;

    }

 

fseek(file_stream,0,2); //定位到文件末尾

    filelenth = ftell(file_stream); //获取文件总长度

 

fseek(file_stream,0,0); //定位文件开头

 

    buffer = (char *)malloc(filelenth);  //动态分配内存

 

    count = fread(buffer, sizeof(char), filelenth, file_stream);  //

    lr_output_message ("%d bytes read", count);

 

    lr_output_message ("content read = %s", buffer );

 

    // Close the file stream

    if (fclose(file_stream))

    {

        lr_error_message ("Error closing file %s", filename);

    }

 

    return buffer;

}

 

 

Action()

{

    char *pt = NULL;

pt = testfn();

    lr_save_string(lr_eval_string(pt), "param");

lr_output_message("value of param: %s",lr_eval_string("{param}"));

 

free(pt); //释放内存

}

 

运行结果：
