Function dmd.root.string.toCStringThen

Copy the content of src into a C-string ('\0' terminated) then call dg

auto toCStringThen(alias dg) (
  const(char)[] src
) nothrow;

The intent of this function is to provide an allocation-less way to call a C function using a D slice. The function internally allocates a buffer if needed, but frees it on exit.


The argument to dg is scope. To keep the data around after dg exits, one has to copy it.


src Slice to use to call the C function
dg Delegate to call afterwards


The return value of T
