gnutls_x509_crt_get_dn(3) gnutls gnutls_x509_crt_get_dn(3)
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);
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 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.
