uint readfln(alias format, Data...)(auto ref Data data) if (isSomeString!(typeof(format)))Reads a line from the file and parses it using formattedRead.
format | The format string. When passed as a compile-time argument, the string will be statically checked against the argument types passed. |
data | Items to be read. |
formattedRead: the number of variables filled. If the
input ends early, this number will be less that the number of variables provided.
Example: --- // sum_rows.d void main() { import std.stdio; auto f = File("input"); int a, b, c; while (f.readfln("%d %d %d", a, b, c) == 3) { writeln(a + b + c); } } --- % cat << EOF > input 1 2 3 4 5 6 7 8 9 EOF % rdmd sum_rows.d 6 15 24
