Greetings — I haven't found this specific topic in the archives; apologies
if this has come up before.
Suppose I have a C struct with an embedded char array:
struct fileinfo_t {
char path[256];
};
and I want to convert the path to a Swift String (in order to implement
`description`, say). I
Thanks to Joe and Quinn for their answers. I have a related followup — a
co-worker learning Swift wrote the following function:
func allZerosUUID() -> String {
var allZeros = [UInt8](repeating: 0, count: 32)
return withUnsafePointer(to: &allZeros) { zerosPtr in

that I'm missing, and I'd appreciate any clarification that the list can
