This does not sound like a UDP application. The client must keep track of which portions of the file have been sent, and the server must take care to see that each portion of the file has been received. Then both need some kind of handshake agreement so that the client knows to resend data to the server, or to pause so that the server can finish storing the data (what if the server blocks)?

In short, you're reinventing the wheels of FTP and/or NFS. What makes your application different?

SSL_set_connect_state(3)					      OpenSSL						  SSL_set_connect_state(3)

NAME
SSL_set_connect_state, SSL_get_accept_state - prepare SSL object to work in client or server mode SYNOPSIS
#include <openssl/ssl.h> void SSL_set_connect_state(SSL *ssl); void SSL_set_accept_state(SSL *ssl); DESCRIPTION
SSL_set_connect_state() sets ssl to work in client mode. SSL_set_accept_state() sets ssl to work in server mode. NOTES
When the SSL_CTX object was created with SSL_CTX_new(3), it was either assigned a dedicated client method, a dedicated server method, or a generic method, that can be used for both client and server connections. (The method might have been changed with SSL_CTX_set_ssl_version(3) or SSL_set_ssl_method().) When beginning a new handshake, the SSL engine must know whether it must call the connect (client) or accept (server) routines. Even though it may be clear from the method chosen, whether client or server mode was requested, the handshake routines must be explicitly set. When using the SSL_connect(3) or SSL_accept(3) routines, the correct handshake routines are automatically set. When performing a transparent negotiation using SSL_write(3) or SSL_read(3), the handshake routines must be explicitly set in advance using either SSL_set_connect_state() or SSL_set_accept_state(). RETURN VALUES
SSL_set_connect_state() and SSL_set_accept_state() do not return diagnostic information. SEE ALSO
ssl(3), SSL_new(3), SSL_CTX_new(3), SSL_connect(3), SSL_accept(3), SSL_write(3), SSL_read(3), SSL_do_handshake(3), SSL_CTX_set_ssl_version(3) 1.0.1e 2013-02-11 SSL_set_connect_state(3)
