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：
