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