(我有一个字符串变量，内容如下：)

varMessage =   
            "hi/thsid/sdfhsjdf/dfjsd/sdjfsdn

            "/my/name/is/balaji.so
"
            "call::myFunction(int const&)
"
            "void::secondFunction(char const&)
"
             .
             .
             .
            "this/is/last/line/liobrary.so"

in above string i have to find a sub string ie

(在上面的字符串我必须找到一个子字符串即)

"hi/thsid/sdfhsjdf/dfjsd/sdjfsdn
"


"/my/name/is/balaji.so
"
"call::myFunction(int const&)
"

How can I find it?

I just need to determine whether the substring is present or not.

(我只需要确定子串是否存在。)
