The CertFreeCRLContext function frees a certificate revocation list (CRL) context by decrementing its reference count. When the reference count goes to zero, CertFreeCRLContext frees the memory occupied by a CRL 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.
