PFN_CERT_STORE_PROV_READ_CTL callback function (wincrypt.h)

The CertStoreProvReadCTL callback function is called to read the provider's copy of the CTL context and, if it exists, to create a new CTL context. Currently, this callback function is not called directly by the store APIs but it can be exported to support other providers based on it.

Syntax

C++

PFN_CERT_STORE_PROV_READ_CTL PfnCertStoreProvReadCtl;

BOOL PfnCertStoreProvReadCtl(
  [in]  HCERTSTOREPROV hStoreProv,
  [in]  PCCTL_CONTEXT pStoreCtlContext,
  [in]  DWORD dwFlags,
  [out] PCCTL_CONTEXT *ppProvCtlContext
)
{...}

Parameters

[in] hStoreProv

HCERTSTOREPROV handle to a certificate store.

[in] pStoreCtlContext

A pointer to a CTL_CONTEXT structure.

[in] dwFlags

Any needed flag values.

[out] ppProvCtlContext

A pointer to a pointer to a CTL_CONTEXT structure to be returned by the function. The context will be freed by calling CertFreeCTLContext.

Return value

Returns TRUE if the function succeeds or FALSE if it fails.
