1. are you allocating buf first?

2. if the socket is non blocking you must use select or poll to notify you when to read/write/accept etc.

ssl_get_accept_state

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.
