gnutls_certificate_get_x509_crt(3)

NAME
gnutls_certificate_get_x509_crt - API function

SYNOPSIS
#include <gnutls/gnutls.h>

int gnutls_certificate_get_x509_crt(gnutls_certificate_credentials_t res, unsigned index, gnutls_x509_crt_t ** crt_list, unsigned * crt_list_size);

ARGUMENTS

gnutls_certificate_credentials_t res
    is a gnutls_certificate_credentials_t type.

unsigned index
    The index of the certificate list to obtain.

gnutls_x509_crt_t ** crt_list
    Where to store the certificate list.

unsigned * crt_list_size
    Will hold the number of certificates.

DESCRIPTION
Obtains a X.509 certificate list that has been stored in res with one of gnutls_certificate_set_x509_key(), gnutls_certificate_set_key(), gnutls_certificate_set_x509_key_file(), gnutls_certificate_set_x509_key_file2(), gnutls_certificate_set_x509_key_mem(), or gnutls_certificate_set_x509_key_mem2(). Each certificate in the returned certificate list must be deallocated with gnutls_x509_crt_deinit(), and the list itself must be freed with gnutls_free(). The index matches the return value of gnutls_certificate_set_x509_key() and friends functions, when the GNUTLS_CERTIFICATE_API_V2 flag is set. If there is no certificate with the given index, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned. If the certificate with the given index is not a X.509 certificate, GNUTLS_E_INVALID_REQUEST is returned. The returned certificates must be deinitialized after use, and the crt_list pointer must be freed using gnutls_free().

RETURNS
GNUTLS_E_SUCCESS (0) on success, or a negative error code.

SINCE
3.4.0
