       gnutls_x509_crq_get_key_purpose_oid - API function
       #include <gnutls/x509.h>
       int gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t crq,
       unsigned indx, void * oid, size_t * sizeof_oid, unsigned int *
       critical);
       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type
       unsigned indx
                   This specifies which OID to return, use (0) to get the
                   first one
       void * oid  a pointer to store the OID (may be NULL)
       size_t * sizeof_oid
                   initially holds the size of  oid
       unsigned int * critical
                   output variable with critical flag, may be NULL.
       This function will extract the key purpose OIDs of the Certificate
       specified by the given index.  These are stored in the Extended
       Key Usage extension (2.5.29.37).  See the GNUTLS_KP_* definitions
       for human readable names.
       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long
       enough, and in that case the * sizeof_oid will be updated with the
       required size.  On success 0 is returned.
