CertEnumCTLContextProperties function (wincrypt.h)

The CertEnumCTLContextProperties function retrieves the first or next extended property associated with a certificate trust list (CTL) context. Used in a loop, this function can retrieve in sequence all extended properties associated with a CTL context.


DWORD CertEnumCTLContextProperties(
  [in] PCCTL_CONTEXT pCtlContext,
  [in] DWORD         dwPropId


[in] pCtlContext

A pointer to a CTL_CONTEXT structure.

[in] dwPropId

Property number of the last property enumerated. To get the first property, dwPropId is zero. To retrieve subsequent properties, dwPropId is set to the property number returned by the last call to the function. To enumerate all the properties, function calls continue until the function returns zero.

Applications can call CertGetCTLContextProperty with the dwPropId returned by this function to retrieved that property's data.

Return value

The return value is a DWORD value that identifies a CTL context's property. The DWORD value returned by one call of the function can be supplied as the dwPropId in a subsequent call to the function. If there are no more properties to be enumerated or if the function fails, zero is returned.
