The documentation at https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/InteractingWithCAPIs.html shows that it is possible to use String where an UnsafePointer<Int8> is needed. API calls to C that need a char* are translated to UnsafePointer<Int8>. It follows that we can use a String where a char* is needed.
However in C a string is not only a char*, it is also null-terminated. What I cannot find though is the guarantee that the buffer where the String is converted to an UTF8 sequence is always null-terminated. I very much suspect it is, and all my tests did find a null-terminated string. Question: Does anybody know for sure that the buffer is always null-terminated? (a link to where I can check this would be most appreciated) Regards, Rien Site: http://balancingrock.nl Blog: http://swiftrien.blogspot.com Github: http://github.com/Swiftrien Project: http://swiftfire.nl
