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.
