NAME

gnutls_x509_crt_get_extension_oid - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, unsigned indx, void * oid, size_t * oid_size);

ARGUMENTS

gnutls_x509_crt_t cert: should contain a gnutls_x509_crt_t type
unsigned indx: Specifies which extension OID to send. Use (0) to get the first one.
void * oid: a pointer to a structure to hold the OID (may be null)
size_t * oid_size: initially holds the size of oid

DESCRIPTION

This function will return the requested extension OID in the certificate. The extension OID will be stored as a string in the provided buffer.

The oid returned will be null terminated, although oid_size will not account for the trailing null.

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.
