NAME¶

gnutls_ocsp_resp_get_extension - API function

SYNOPSIS¶

#include <gnutls/ocsp.h>

int gnutls_ocsp_resp_get_extension(gnutls_ocsp_resp_const_t resp, unsigned indx, gnutls_datum_t * oid, unsigned int * critical, gnutls_datum_t * data);

ARGUMENTS¶

gnutls_ocsp_resp_const_t resp

should contain a gnutls_ocsp_resp_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

DESCRIPTION¶

This function will return all information about the requested extension in the OCSP response. 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.

RETURNS¶

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.
