NAME

       gnutls_x509_crt_get_extension_data - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t  cert,  int  indx,  void * data,
       size_t * sizeof_data);

ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t structure

       int indx    Specifies which extension OID to send. Use zero to get the first one.

       void * data a pointer to a structure to hold the data (may be null)

       size_t * sizeof_data
                   initially holds the size of oid

DESCRIPTION

       This function will return the requested extension data in the certificate.  The  extension
       data will be stored as a string in the provided buffer.

       Use  gnutls_x509_crt_get_extension_info()  to  extract  the  OID  and  critical flag.  Use
       gnutls_x509_crt_get_extension_by_oid() instead, if you want to get  data  indexed  by  the
       extension OID rather than sequence.

RETURNS

       On  success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned.  If
       you have reached the last extension available  GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE  will
       be returned.
