WOLFSSL_API void wolfSSL_CTX_SetGenCookie(WOLFSSL_CTX *, CallbackGenCookie)
This function sets the callback for the CBIOCookie member of the WOLFSSL_CTX structure. The CallbackGenCookie type is a function pointer and has the signature: int (CallbackGenCookie)(WOLFSSL ssl, unsigned char* buf, int sz, void* ctx);.

WOLFSSL_API void wolfSSL_CTX_SetIORecv(WOLFSSL_CTX *, CallbackIORecv)
This function registers a receive callback for wolfSSL to get input data. By default, wolfSSL uses EmbedReceive() as the callback which uses the system’s TCP recv() function. The user can register a function to get input from memory, some other network module, or from anywhere. Please see the EmbedReceive() function in src/io.c as a guide for how the function should work and for error codes. In particular, IO_ERR_WANT_READ should be returned for non blocking receive when no data is ready.

WOLFSSL_API int EmbedSend(WOLFSSL *ssl, char *buf, int sz, void *ctx)
This function is the send embedded callback.

WOLFSSL_API void wolfSSL_SetIOReadFlags(WOLFSSL *ssl, int flags)
This function sets the flags for the receive callback to use for the given SSL session. The receive callback could be either the default wolfSSL EmbedReceive callback, or a custom callback specified by the user (see wolfSSL_CTX_SetIORecv). The default flag value is set internally by wolfSSL to the value of 0. The default wolfSSL receive callback uses the recv() function to receive data from the socket. From the recv() man page: “The flags argument to a recv() function is formed by or'ing one or more of the values: MSG_OOB process out-of-band data, MSG_PEEK peek at incoming message, MSG_WAITALL wait for full request or error. The MSG_OOB flag requests receipt of out-of-band data that would not be received in the normal data stream. Some protocols place expedited data at the head of the normal data queue, and thus this flag cannot be used with such protocols. The MSG_PEEK flag causes the receive operation to return data from the beginning of the receive queue without removing that data from the queue. Thus, a subsequent receive call will return the same data. The MSG_WAITALL flag requests that the operation block until the full request is satisfied. However, the call may still return less data than requested if a signal is caught, an error or disconnect occurs, or the next data to be received is of a different type than that returned.”

WOLFSSL_API void wolfSSL_SetIOWriteFlags(WOLFSSL *ssl, int flags)
This function sets the flags for the send callback to use for the given SSL session. The send callback could be either the default wolfSSL EmbedSend callback, or a custom callback specified by the user (see wolfSSL_CTX_SetIOSend). The default flag value is set internally by wolfSSL to the value of 0. The default wolfSSL send callback uses the send() function to send data from the socket. From the send() man page: “The flags parameter may include one or more of the following: #define MSG_OOB 0x1 // process out-of-band data, #define MSG_DONTROUTE 0x4 // bypass routing, use direct interface. The flag MSG_OOB is used to send `‘out-of-band’' data on sockets that support this notion (e.g. SOCK_STREAM); the underlying protocol must also support `‘out-of-band’' data. MSG_DONTROUTE is usually used only by diagnostic or routing programs.”

WOLFSSL_API void wolfSSL_SetIOReadCtx(WOLFSSL *ssl, void *ctx)
This function registers a context for the SSL session’s receive callback function. By default, wolfSSL sets the file descriptor passed to wolfSSL_set_fd() as the context when wolfSSL is using the system’s TCP library. If you’ve registered your own receive callback you may want to set a specific context for the session. For example, if you’re using memory buffers the context may be a pointer to a structure describing where and how to access the memory buffers.
