NAME         top

       gnutls_x509_crq_get_key_purpose_oid - API function

SYNOPSIS         top

       #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 *

ARGUMENTS         top

       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.
