       gnutls_x509_crt_get_dn - API function

SYNOPSIS        top

#include <gnutls/x509.h>int gnutls_x509_crt_get_dn(gnutls_x509_crt_tcert, char *buf,size_t *buf_size);

ARGUMENTS        top

       gnutls_x509_crt_t cert                   should contain agnutls_x509_crt_ttype       char * buf  a pointer to a structure to hold the name (may be                   null)       size_t * buf_size                   initially holds the size ofbuf

DESCRIPTION        top

       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.       Thebuf returned will be null terminated and thebuf_size will       account for the trailing null. Ifbuf is null then only the size       will be filled.       This function does not output a fully RFC4514 compliant string, if       that is required seegnutls_x509_crt_get_dn3().

RETURNS        top

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