NAME

gnutls_x509_trust_list_get_issuer - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_trust_list_get_issuer(gnutls_x509_trust_list_t list, gnutls_x509_crt_t cert, gnutls_x509_crt_t * issuer, unsigned int flags);

ARGUMENTS

gnutls_x509_trust_list_t list: The list
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: flags from gnutls_trust_list_flags_t (GNUTLS_TL_GET_COPY is applicable)

DESCRIPTION

This function will find the issuer of the 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.

Note that the flag GNUTLS_TL_GET_COPY is required for this function to work 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
