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
