copy_normalize_addr()

static struct Address * copy_normalize_addr ( struct Address *  addr )

Copy a normalised Email Address.

Parameters

addr	Address to normalise and copy

Return values

ptr	Copy of the Address

The autocrypt spec says email addresses should be normalized to lower case and stored in idna form.

In order to avoid visible changes to addresses in the index, we make a copy of the address before lowercasing it.

Note

The return value must be freed

Definition at line 202 of file db.c.

  /* NOTE: the db functions expect a single address, so in
   * this function we copy only the address passed in.
