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

ARGUMENTS

       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.

DESCRIPTION

       This function will extract the key purpose OIDs of the Certificate specified by the  given

       GNUTLS_KP_* definitions for human readable names.

RETURNS

       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.

SINCE
