       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,  unsigned  indx,  void  *  oid,  size_t *
       sizeof_oid);

ARGUMENTS

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       unsigned 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.
