gnutls_x509_crt_get_dn - API function

#include <gnutls/x509.h>

int gnutls_x509_crt_get_dn(gnutls_x509_crt_t cert, char * buf, size_t * buf_size);

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

This function will copy the name of the Certificate 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.

The buf returned will be null terminated and the buf_size will account for the trailing null. If buf is null then only the size will be filled.

This function does not output a fully RFC4514 compliant string, if that is required see gnutls_x509_crt_get_dn3().

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.
