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
				

				);
				

				

				static extern(C++) bool update
				(
				

				  const(char)* name,
				

				  const(void)* data,
				

				  ulong size
				

				);

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.

Parameters

Name	Description
name	name of file to update
data	updated contents of file

Returns

true on success
