       gnutls_x509_crq_get_attribute_info - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
       negative error code in case of an error.  If your have reached
