NAME
       gnutls_x509_crq_get_extension_by_oid - API function


SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t  crq, const char * oid, unsigned indx, void *
       buf, size_t * buf_size, unsigned int * critical);


ARGUMENTS
       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       const char * oid
                   holds an Object Identifier in a null terminated string

       unsigned indx
                   In case multiple same OIDs exist in the extensions, this specifies which to get. Use  (0)  to
                   get the first one.

       void * buf  a pointer to a structure to hold the name (may be null)

       size_t * buf_size
                   initially holds the size of  buf

       unsigned int * critical
                   will be non-zero if the extension is marked as critical


DESCRIPTION
       This  function will return the extension specified by the OID in the certificate.  The extensions will be
       returned as binary data DER encoded, in the provided buffer.


RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of  an  error.   If
       the  certificate  does  not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be
       returned.


SINCE
       2.8.0
