// Parameters:
//	A cp3000_device_t object
//	id - Name of the fifo
// Remarks:
//	- Clients are accepted by cp3000_accept_client().
//	- The path to the fifo is stored in the configuration (CFG_FIFO_DIR)
//	- SSL maybe overkill on a Unix socket

// Connect to a server

// Returns:
//	0 on success, -1 on error
// Remarks:
