gnutls_ocsp_req_get_extension - Man Page

API function


#include <gnutls/ocsp.h>

int gnutls_ocsp_req_get_extension(gnutls_ocsp_req_const_t req, unsigned indx, gnutls_datum_t * oid, unsigned int * critical, gnutls_datum_t * data);


gnutls_ocsp_req_const_t req

should contain a gnutls_ocsp_req_t type

unsigned indx

Specifies which extension OID to get. Use (0) to get the first one.

gnutls_datum_t * oid

will hold newly allocated buffer with OID of extension, may be NULL

unsigned int * critical

output variable with critical flag, may be NULL.

gnutls_datum_t * data

will hold newly allocated buffer with extension data, may be NULL


This function will return all information about the requested extension in the OCSP request.  The information returned is the OID, the critical flag, and the data itself.  The extension OID will be stored as a string.  Any of  oid ,  critical , and  data may be NULL which means that the caller is not interested in getting that information back.

The caller needs to deallocate memory by calling gnutls_free() on
oid ->data and  data ->data.

Since 3.7.0  oid ->size does not account for the terminating null byte.


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.  If you have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
