1=pod 2 3=head1 NAME 4 5SSL_inject_net_dgram - inject a datagram as though received from the network 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 int SSL_inject_net_dgram(SSL *s, const unsigned char *buf, 12 size_t buf_len, 13 const BIO_ADDR *peer, 14 const BIO_ADDR *local); 15 16=head1 DESCRIPTION 17 18This function can be used to inject a datagram payload to a QUIC connection SSL 19object. The payload is processed as though it was received from the network. 20This function can be used for debugging purposes or to allow datagrams to be fed 21to QUIC from alternative sources. 22 23I<buf> is required and must point to a datagram payload to inject. I<buf_len> is 24the length of the buffer in bytes. The buffer is copied and need not remain 25valid after this function returns. 26 27I<peer> and I<local> are optional values pointing to B<BIO_ADDR> structures 28describing the remote and local UDP endpoint addresses for the packet. Though 29the injected packet was not actually received from the network directly by 30OpenSSL, the packet will be processed as though the received datagram had the 31given addresses. 32 33=head1 RETURN VALUES 34 35Returns 1 on success or 0 on failure. This function always fails if called 36on an SSL object which is not a QUIC connection SSL object. 37 38=head1 SEE ALSO 39 40L<OSSL_QUIC_client_method(3)>, L<SSL_handle_events(3)>, L<SSL_set_blocking_mode(3)> 41 42=head1 HISTORY 43 44The function SSL_inject_net_dgram() was added in OpenSSL 3.2. 45 46=head1 COPYRIGHT 47 48Copyright 2023 The OpenSSL Project Authors.
