Initializer

init(cStringNoCopy:length:freeWhenDone:)

Initializes the receiver, a newly allocated NSString object, by converting the data in a given C-string from the default C-string encoding into the Unicode character encoding.

Declaration

convenience init?(cStringNoCopy bytes: UnsafeMutablePointer<Int8>, length: Int, freeWhenDone freeBuffer: Bool)

Discussion

This method converts length * sizeof(char) bytes from cString and doesn’t stop short at a zero character. cString must contain data in the default C-string encoding and may not be NULL. The receiver becomes the owner of cString; if flag is true it will free the memory when it no longer needs it, but if flag is false it won’t. Returns an initialized object, which might be different from the original receiver.

You can use this method to create an immutable string from an immutable (const char *) C-string buffer. If you receive a warning message, you can disregard it; its purpose is simply to warn you that the C string passed as the method’s first argument may be modified. If you make certain the freeWhenDone argument to initWithStringNoCopy is false, the C string passed as the method’s first argument cannot be modified, so you can safely use initWithStringNoCopy to create an immutable string from an immutable (const char *) C-string buffer.
