how can i get a certificate's root certificate ?

for example:
i have a certificate issued by "Thawte Personal Freemail Issuing CA"
but "Thawte Personal Freemail Issuing CA" is issued by "Thawte Personal
Freemail CA"

it can be show as :

Thawte Personal Freemail CA
|
---------------Thawte Personal Freemail Issuing CA
|
_______________________Thawte Freemail
member


here is my question:
how can i export "Thawte Personal Freemail CA" 's certificate

now i can only export "Thawte Freemail member"'s certificate,
because i know the user's email ,so i can use email to findout it's
certificate


if ( !( hCertStore = CertSystemStore(
L"AddressBook")))
{... }

// Get the certificate for the signer.
if(!(pSignerCertContext = CertFindCertificateInStore(
hCertStore,
MY_TYPE,
0,
CERT_FIND_SUBJECT_STR,
"user@xxxxxxxxx",
NULL)))
{
...
}


but i don't know anything about the root certificate

is there any api i can refer to ?


thank you.
