const char *id,
Create a new handle for verifying a (possibly) signed message.
||dkim_verify() is called when preparing to process a new message
that may be signed already in order to be able to verify its contents
against the signature.
||DKIM library instance handle, returned by
an earlier call to dkim_init().
||An opaque, printable string for identifying this message,
suitable for use in logging or debug output.
||Opaque memory closure, passed directly to the caller-provided
malloc() and/or free() replacement functions.
||Pointer to a DKIM_STAT
object which receives the completion status of this operation.
- The handle returned by this function may not be used in a later call
- On success, a pointer to the created DKIM
handle is returned.
- On failure, NULL is returned and the value of statp is updated
to indicate the cause of the problem.
