Function dmd.root.file.File.update

Update file

static bool update (
  const(char)* namez,
  const(void[]) data

static bool update (
  const(char)[] name,
  const(void[]) data

If the file exists and is identical to what is to be written, merely update the timestamp on the file. Otherwise, write the file.

The idea is writes are much slower than reads, and build systems often wind up generating identical files.


name name of file to update
data updated contents of file


true on success
