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.

Note

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

Parameters

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

Returns

The return value of T
