This is NSS with a Cmake Buildsyste To compile a static NSS library for Windows we've used the Chromium-NSS fork and added a Cmake buildsystem to compile it statically for Windows. See README.chromium for chromium changes and README.trustbridge for our modifications.

217 * FUNCTION: pkix_pl_OcspRequest_Create
218 * DESCRIPTION:
219 *
220 * This function creates an OcspRequest to be used in validating the Cert
221 * pointed to by "cert" and storing the result at "pRequest". If a URI
222 * is found for an OCSP responder, PKIX_TRUE is stored at "pURIFound". If no
223 * URI is found, PKIX_FALSE is stored.
224 *
225 * If a Date is provided in "validity" it may be used in the search for the
226 * issuer of "cert" but has no effect on the request itself. If
227 * "addServiceLocator" is TRUE, the AddServiceLocator extension will be
228 * included in the Request. If "signerCert" is provided it will be used to sign
229 * the Request. (Note: this signed request feature is not currently supported.)
230 *
231 * PARAMETERS:
232 * "cert"
233 * Address of the Cert for which an OcspRequest is to be created. Must be
234 * non-NULL.
235 * "validity"
236 * Address of the Date for which the Cert's validity is to be determined.
237 * May be NULL.
238 * "signerCert"
239 * Address of the Cert to be used, if present, in signing the request.
240 * May be NULL.
241 * "pRequest"
242 * Address at which the result is stored. Must be non-NULL.
243 * "plContext"
244 * Platform-specific context pointer.
245 * THREAD SAFETY:
246 * Thread Safe (see Thread Safety Definitions in Programmer's Guide)
247 * RETURNS:
248 * Returns NULL if the function succeeds.
249 * Returns an OcspRequest Error if the function fails in a non-fatal way.
250 * Returns a Fatal Error if the function fails in an unrecoverable way.
