在LoadRunner中转换字符串大小写的C语言函数

在LoadRunner中转换字符串大小写的C语言函数   .   loadrunner语言ccharacterstringaction      封装ConvertToXXX函数：  //ConvertToUpper function  int ConvertToUpper(char * sInput, char * sNew)  {   sInput = (char *)strupr(sInput);   lr_save_string(sInput,sNew);  }     //ConvertToLower function  int ConvertToLower(char * sInput, char * sNew)  {   sInput = (char *)strlwr(sInput);   lr_save_string(sInput,sNew);  }     //ConvertToTitle function  int ConvertToTitle(char * sInput, char * sNew)  {   int i = 0, s = 0, l = 0;   char buf1[50];   char buf2[2];   char n;      // Copy a single character into the address of [n]   strncpy(&n,sInput+i,1);   // Copy the single character into buf2   sprintf(buf2,"%c",n);   // Convert the contents of buf2 to uppercase   strupr(buf2);   // Overwrite the contents of buf1 with buf2   strcpy(buf1,buf2);   i++;   while(i < strlen(sInput))   {    // Overwrite buf2 with one character    strncpy(&n,sInput+i,1);    sprintf(buf2,"%c",n);    // If the previous character was a space then make the current character upper case    if(s == 1){     strupr(buf2);     strcat(buf1,buf2);     s = 0;    }    // Otherwise convert to lower case and concatenate the current character into the string buf1    else{     strlwr(buf2);     strcat(buf1,buf2);    }    // If the current character is a space set the value of [s] to [1] so that the next character gets capitalised    if(strcmp(" ",buf2)==0)    {     s = 1;    }    i++;   }   lr_save_string(buf1,sNew);  }     使用ConvertToXXX转换函数：  Action()  {         lr_save_string("testing is believing","str");         ConvertToUpper(lr_eval_string("{str}"),"UpperStr");         lr_output_message(lr_eval_string("{UpperStr}"));         ConvertToLower(lr_eval_string("{str}"),"LowerStr");         lr_output_message(lr_eval_string("{LowerStr}"));            ConvertToTitle(lr_eval_string("{str}"),"TitleStr");         lr_output_message(lr_eval_string("{TitleStr}"));            return 0;  }     输出：  Virtual User Script started at : 2010-01-30 17:53:13  Starting action vuser_init.
