CertDuplicateCertificateChain function (wincrypt.h)

The CertDuplicateCertificateChain function duplicates a pointer to a certificate chain by incrementing the chain's reference count.

Syntax

PCCERT_CHAIN_CONTEXT CertDuplicateCertificateChain(
  [in] PCCERT_CHAIN_CONTEXT pChainContext
);

Parameters

[in] pChainContext

A pointer to a CERT_CHAIN_CONTEXT chain context to be duplicated.

Return value

If the function succeeds, a pointer is returned to the chain context. This pointer has the same value as the pChainContext passed into the function. When you have finished using the chain context, release the chain context by calling the CertFreeCertificateChain function.
