Name

gnutls_x509_crq_get_extension_by_oid — API function

Synopsis

#include <gnutls/x509.h>

`int gnutls_x509_crq_get_extension_by_oid(`	gnutls_x509_crq_t `crq`,
	const char * `oid`,
	int `indx`,
	void * `buf`,
	size_t * `buf_size`,
	unsigned int * `critical)`;

ARGUMENTS

gnutls_x509_crq_t crq: should contain a gnutls_x509_crq_t structure
const char * oid: holds an Object Identifier in a null terminated string
int indx: In case multiple same OIDs exist in the extensions, this specifies which to get. Use (0) to get the first one.
void * buf: a pointer to a structure to hold the name (may be null)
size_t * buf_size: initially holds the size of buf
unsigned int * critical: will be non−zero if the extension is marked as critical

DESCRIPTION

This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer.

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE

2.8.0
