June 24, 2010 TDPL's use of readf | ||||
---|---|---|---|---|
| ||||
On page 22 of TDPL, we have the following code: import std.contracts, std.stdio; void main(string[] args) { // ... for (double x; readf(" %s ", &x) == 1; ) { // ... } // ... } Using DMD v2.047, I get the following error on the readf call: Error: undefined identifier readf, did you mean function readln? I didn't see this mentioned in the TDPL errata. Was there a change to the standard library after the book went to press? Or am I doing something wrong? Thanks, Jeff |

Andrei talked about that on the digitalmars.D list. He forgot to check in the code for it, so it's not in v2.047. However, I believe that he's checked it into the svn version, so readf should be in v2.048 when that comes out.
