NAME

gnutls_ocsp_req_get_extension - API function

SYNOPSIS

#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);

ARGUMENTS

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

DESCRIPTION

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.

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.
