CVMFS_EXPORT bool String2Uint64Parse ( const std::string &  value,
uint64_t *  result 

Parse a string into a a uint64_t.

Unlike String2Uint64, this:

  • Checks to make sure the full string is parsed
  • Can indicate an error occurred.

If an error occurs, this returns false and sets errno appropriately.
