loadrunner中大小写字符转换函数封装：

//封装ConvertToXXX函数：

int ConvertToUpper(char * sInput, char * sNew)

{

sInput = (char *)strupr(sInput);

lr_save_string(sInput,sNew);

}

int ConvertToLower(char * sInput, char * sNew)

{

sInput = (char *)strlwr(sInput);

lr_save_string(sInput,sNew);

}

int ConvertToTitle(char * sInput, char * sNew)

{

int i = 0, s = 0, l = 0;

char buf1[50];

char buf2[2];

char n;

strncpy(&n,sInput+i,1);

sprintf(buf2,"%c",n);

strupr(buf2);

strcpy(buf1,buf2);

i++;

while(i < strlen(sInput))
