-// IMPORTANT MESSAGE FROM YOUR SPONSOR
-//
-// This file contains no "wstring" variants. New code should use string16. If
-// you need to make old code work, use the UTF8 version and convert. Please do
-// not add wstring variants.
-//
-// Please do not add "convenience" functions for converting strings to integers
-// that return the value and ignore success/failure. That encourages people to
-// write code that doesn't properly handle the error conditions.

-//    by the data type.
-//  - Trailing characters in the string after parsing the number.  |*output|
-//    will be set to the value of the number that was parsed.
-//  - Leading whitespace in the string before parsing the number. |*output| will
-//    be set to the value of the number that was parsed.
-//  - No characters parseable as a number at the beginning of the string.
-//    |*output| will be set to 0.
-//  - Empty string.  |*output| will be set to 0.
