The following code example demonstrates how you can send a message, using first the cmc_send and then the cmc_send_documents function.
/* Local variables used */
CMC_attachment Attach;
CMC_session_id Session;
CMC_message Message;
CMC_recipient Recip[2];
CMC_return_code Status;
CMC_time t_now;

Recip[0].address = NULL; /* Look_up Bob's address. */
Recip[0].role = CMC_ROLE_TO; /* He's a "To" recipient. */
Recip[0].recip_flags= 0; /* Not the last element */
Recip[0].recip_extensions = NULL; /* No recipient extensions */
/* Add one "Cc" recipient. */
Recip[1].name = "Mary Yu"; /* Send to Mary Yu. */
Recip[1].name_type = CMC_TYPE_INDIVIDUAL; /* Mary's a person. */
Recip[1].address = NULL; /* Look_up Mary's address. */

Attach.attach_flags = CMC_ATT_LAST_ELEMENT; /* Last attachment */
