CertDuplicateCTLContext function (wincrypt.h)

  • Article

The CertDuplicateCTLContext function duplicates a certificate trust list (CTL) context by incrementing its reference count.

Syntax

PCCTL_CONTEXT CertDuplicateCTLContext(
  [in] PCCTL_CONTEXT pCtlContext
);

Parameters

[in] pCtlContext

A pointer to the CTL_CONTEXT structure for which the reference count is being incremented.

Return value

Currently, a copy is not made of the context, and the returned pointer to CTL_CONTEXT is the same as pointer input. If the pointer passed into this function is NULL, NULL is returned.
