@brief Get session context from socket descriptor

Typically if a session context is created, it is available to URI handlers through the httpd_req_t structure. But, there are cases where the web server’s send/receive functions may require the context (for example, for accessing keying information etc). Since the send/receive function only have the socket descriptor at their disposal, this API provides them with a way to retrieve the session context.

@param[in] handle Handle to server returned by httpd_start @param[in] sockfd The socket descriptor for which the context should be extracted.

@return

• void* : Pointer to the context associated with this session
• NULL : Empty context / Invalid handle / Invalid socket fd
