// lr_convert_string_encoding 在下列编码之间转换字符串编码:系统区域设置、Unicode 和 UTF-8。

// 该函数将结果字符串(包括其终止 // 结果字符串 NULL)保存在参数 paramName 中。

// lr_output_message 函数将带有脚本部分和行号的消息 // 发送到输出窗口和日志文件。 int lr_output_message (const char * format, exp1, exp2,...expn.);

-- Sends a Vuser message to the log file and output window with location information.

// lr_log_message -- Sends a message to the Vuser log file.

// lr_message -- Sends a message to the log file and output window. 

// lr_save_string 函数将指定的以 null 终止的 // 字符串赋给参数。该函数可用于关联 // 查询。要确定参数值,请使用 // 函数 lr_eval_string。

HP LoadRunner Online Function Reference > C Language Functions > Example: strcpy

// strcat 连接两个字符串。 char *strcat ( char *to, const char *from );

-- The following example uses strcat to append a backslash to the directory name, fullpath. It then appends filename to fullpath.

// strcpy 将一个字符串复制给另一个。 char *strcpy ( char *dest, const char *source );

-- The following example uses strcpy to copy the string "c:\\tmp" to the character array fullpath.

Action()
{
	 char fullpath[1024], *filename = "logfile.txt";

     strcpy(fullpath, "c:\\tmp");

	 lr_output_message("fullpath after strcpy: %s", fullpath);
	 strcat(fullpath, "\\");

LoadRunner lr_eval_string() 函数使用及LR中变量、参数的简单使用

http://blog.csdn.net/oobibigo/article/details/3321558

lr_eval_string()

函数的主要作用：返回脚本中的一个参数当前的值，

返回值类型：char

一般多用在调试脚本时输出参数的值.具体用法如下:
lr_output_message("The parameter1's value is %s",lr_eval_string("{parameter1}")),其中参数parameter1在之前已经定义了的参数

lr_log_message(lr_eval_string("{parameter1}"))

1.参数的赋值和取值

lr_save_string("hello world","param");
lr_eval_string("{param}");
2.变量到参数
int x;
x=10;
lr_save_string(x,"param");
lr_eval_string("{param}");
3.变量读参数
char x[100];
x="{param}";
lr_save_string("hello world","param");
lr_eval_string(x);
