krb5_error_code `krb5_merge_authdata`(krb5_context context, krb5_authdata *const * inauthdat1, krb5_authdata *const * inauthdat2, krb5_authdata *** outauthdat)

param: | [in] context - Library context [in] inauthdat1 - First list of krb5_authdata structures [in] inauthdat2 - Second list of krb5_authdata structures [out] outauthdat - Merged list of krb5_authdata structures

retval: | 0 Success; otherwise - Kerberos error codes

Merge two authdata arrays, such as the array from a ticket and authenticator. Use `krb5_free_authdata()` to free outauthdat when it is no longer needed.

Note

The last array entry in inauthdat1 and inauthdat2 must be a NULL pointer.
