SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int   gnutls_x509_trust_list_get_issuer(gnutls_x509_trust_list_t  list,
12       gnutls_x509_crt_t  cert,  gnutls_x509_crt_t  *  issuer,  unsigned   int
13       flags);
14

ARGUMENTS

16       gnutls_x509_trust_list_t list
17                   The list
18
19       gnutls_x509_crt_t cert
20                   is the certificate to find issuer for
21
22       gnutls_x509_crt_t * issuer
23                   Will hold the issuer if any. Should be treated as constant.
24
25       unsigned int flags
26                   flags from gnutls_trust_list_flags_t (GNUTLS_TL_GET_COPY is
27                   applicable)
28

DESCRIPTION

30       This function will find the issuer of the given  certificate.   If  the
31       flag  GNUTLS_TL_GET_COPY  is  specified  a  copy  of the issuer will be
32       returned which must be freed using gnutls_x509_crt_deinit().   In  that
33       case the provided  issuer must not be initialized.
34
35       Note  that the flag GNUTLS_TL_GET_COPY is required for this function to
36       work with PKCS11 trust lists in a thread-safe way.
37

RETURNS

39       On success, GNUTLS_E_SUCCESS (0)  is  returned,  otherwise  a  negative
40       error value.
