How to convert nsstring to cString?

Question

I have a nsstring(filePath),which has the path to the audio file.I want open the audio file, so i want to convert the nsstring to Cstring.

  fopen([filePath cStringUsingEncoding:1], "r");

is the above line is correct or not,because i can also use fopen([filePath cString], "r");, In some websites it is mentioned to use UTF8stringEncoding.Which is the the right NSString to string conversion.Please help me out.Thanks.

Use UTF8String:

fopen([filePath UTF8String], "r");
