CertFindExtension

Windows CE 3.0

This function finds the first extension in the CERT_EXTENSION array, as identified by its object identifier(OID). This function can be used in the processing of a decoded certificate. A CERT_INFO structure is derived from a decoded certificate. The rgExtension array is retrieved from that structure and passed to this function in the rgExtension parameter. This function determines whether a particular extension is in the array, and if so, returns a pointer to it.

PCERT_EXTENSION WINAPI CertFindExtension(
LPCSTR pszObjId,
DWORD cExtensions,
CERT_EXTENSION rgExtensions[ ]
);

Parameters

pszObjId
[in] Pointer to the OID to use in the search.
cExtensions

Return Values
