Instance Method

fileSystemRepresentation(withPath:)

Returns a C-string representation of a given path that properly encodes Unicode strings for use by the file system.

Declaration

func fileSystemRepresentation(withPath path: String) -> UnsafePointer<Int8>

Parameters

path

A string object containing a path to a file. This parameter must not be nil or contain the empty string.

Return Value

A C-string representation of path that properly encodes Unicode strings for use by the file system.

Discussion

Use this method if your code calls system routines that expect C-string path arguments. If you use the C string beyond the scope of the current autorelease pool, you must copy it.

This method raises an exception if path is nil or contains the empty string. This method also throws an exception if the conversion of the string fails.
