Information processing apparatus for interprocess communication to perform processing without requiring completion of preparation for receiving a message

A method of controlling an information processing apparatus including a first device and a second device, the control method comprising:

• a first processing for controlling the first device, wherein the first processing receives information from the first device about a status of the first device and transmits a message to a second processing;
• and
• the second processing for controlling the second device, wherein the second processing receives the message from the first processing and controls the second device,
• wherein, the first processing performs, in a process of a series of startup processes, a process for starting a communication with the second processing, and the second processing performs, in a process of a series of startup processes, a process for starting a communication with the first processing, and
• wherein, the first processing stores predetermined information in a predetermined storage area based on the information about the status of the first device received from the first device in the series of startup processes, and the second processing controls the second device based on the predetermined information acquired from the storage area in the series of startup processes,
• wherein the process for starting the communication with the second processing and the process for starting the communication with the first processing is not synchronized such that control of the second device is dependent on the message or the predetermined information acquired from the storage area in the series of startup processes.

A non-transitory storage medium storing a program for causing a controller to execute a control method of controlling an information processing apparatus including a first device and a second device, the control method comprising:

• first processing for controlling the first device, wherein the first processing receives information from the first device about a status of the first device and transmits a message to a second processing;
• and
• the second processing for controlling the second device, wherein the second processing receives the message from the first processing and controls the second device,
• wherein, the first processing performs, in a process of a series of startup processes, a process for starting a communication with the second processing, and the second processing performs, in a process of a series of startup processes, a process for starting a communication with the first processing, and
• wherein, the first processing stores predetermined information in a predetermined storage area based on the information about the status of the first device received from the first device in the series of startup processes, and the second processing controls the second device based on the predetermined information acquired from the storage area in the series of startup processes,
• wherein the process for starting the communication with the second processing and the process for starting the communication with the first processing is not synchronized such that control of the second device is dependent on the message or the predetermined information acquired from the storage area in the series of startup processes.
