CertFreeCTLContext function (wincrypt.h)

The CertFreeCTLContext function frees a certificate trust list (CTL) context by decrementing its reference count. When the reference count goes to zero, CertFreeCTLContext frees the memory used by a CTL context.

To free a context obtained by a get, duplicate, or create function, call the appropriate free function. To free a context obtained by a find or enumerate function, either pass it in as the previous context parameter to a subsequent invocation of the function, or call the appropriate free function. For more information, see the reference topic for the function that obtains the context.

  [in] PCCTL_CONTEXT pCtlContext
