NAME

       gnutls_x509_crq_get_extension_by_oid - API function


SYNOPSIS

       #include <gnutls/x509.h>

       gnutls_x509_crq_get_extension_by_oid(3)  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.
