       gnutls_x509_crq_get_attribute_info - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid);

ARGUMENTS

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       int indx    Specifies which attribute number to get. Use (0) to get the first one.

       void * oid  a pointer to a structure to hold the OID

       size_t * sizeof_oid
                   initially holds the maximum size of  oid , on return holds actual size of  oid .

DESCRIPTION

       This  function  will return the requested attribute OID in the certificate, and the critical flag for it.
       The   attribute   OID   will   be   stored   as   a    string    in    the    provided    buffer.     Use
       gnutls_x509_crq_get_attribute_data() to extract the data.

       If  the  buffer  provided  is  not  long  enough  to  hold  the  output, then * sizeof_oid is updated and
       GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of  an  error.   If
       your have reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
