### Method

# Soup AuthDomainDigest set_auth_callback

#### Declaration [src]

    void
    soup_auth_domain_digest_set_auth_callback (
      SoupAuthDomain* domain,

      GDestroyNotify dnotify
    )

#### Description [src]

Sets the callback that `domain` will use to authenticate incoming requests.

You can also set the auth callback by setting the `SoupAuthDomainDigest:auth-callback` and `SoupAuthDomainDigest:auth-data` properties, which can also be used to set the callback at construct time.
