gnutls_x509_crt_get_issuer_dn — API function


#include <gnutls/x509.h>

int gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t cert, char * buf, size_t * buf_size);


gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
char * buf
a pointer to a structure to hold the name (may be null)
size_t * buf_size
initially holds the size of buf


This function will copy the name of the Certificate issuer in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514. The output string will be ASCII or UTF-8 encoded, depending on the certificate data.

If buf is null then only the size will be filled.


GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the buf_size will be updated with the required size. GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the DN does not exist, or another error value on error. On success 0 is returned.
