CertFreeCertificateContext function

The CertFreeCertificateContext function frees a certificate context by decrementing its reference count. When the reference count goes to zero, CertFreeCertificateContext frees the memory used by a certificate 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.


BOOL CertFreeCertificateContext(



A pointer to the CERT_CONTEXT to be freed.
