How to convert nsstring to cString?

warrior · 10-26-2010, 12:23 AM

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.

when i tried to read the wave file the output is always caff, so i dont understand which is working or not working. I want to check my concept of opening is right or wrong.

I don't understand this response. Whether the conversion from NSString to C-string in the filename is working or not won't change a file's contents from WAV to CAF.
