NAME

       gnutls_x509_crq_get_key_purpose_oid - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_key_purpose_oid(gnutls_x509_crq_t  crq,  int  indx,  void  * oid,
       size_t * sizeof_oid, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       int 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
