NAME
gnutls_certificate_get_issuer - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int
gnutls_certificate_get_issuer(gnutls_certificate_credentials_t
sc, gnutls_x509_crt_t cert, gnutls_x509_crt_t * issuer, unsigned
int flags);
ARGUMENTS
gnutls_certificate_credentials_t sc
is a gnutls_certificate_credentials_t type.
gnutls_x509_crt_t cert
is the certificate to find issuer for
gnutls_x509_crt_t * issuer
Will hold the issuer if any. Should be treated as
constant.
unsigned int flags
Use zero or GNUTLS_TL_GET_COPY
DESCRIPTION
This function will return the issuer of a given certificate. If
the flag GNUTLS_TL_GET_COPY is specified a copy of the issuer
will be returned which must be freed using
gnutls_x509_crt_deinit(). In that case the provided issuer must
not be initialized.
As with gnutls_x509_trust_list_get_issuer() this function
requires the GNUTLS_TL_GET_COPY flag in order to operate with
PKCS11 trust lists in a thread-safe way.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error value.
SINCE
3.0
