Wait for request from development computer to start or stop external mode simulation

Syntax

Description

[errorCode](#d126e37261) = extmodeWaitForHostRequest([timeoutInMicroseconds](#d126e37233)); waits for a start or stop request from the development computer and times out when the timeout value is reached.

Use this function with other external mode functions to enable communication between Simulink® and the target application during an external mode simulation. Use the function during initialization because the function is a blocking function.

Input Arguments

collapse all

Specifies the timeout value. If the value is set toEXTMODE_WAIT_FOREVER, the function waits indefinitely. If '-w' is not extracted byextmodeParseArgs(), the function has no effect.

Output Arguments

Error code, returned as an extmodeErrorCode_T enumeration with one of these values:

• EXTMODE_SUCCESS (0) –– No error detected.
• EXTMODE_INV_ARG (-1) –– Arguments invalid.
• EXTMODE_TIMEOUT_ERROR (-100) –– External mode timeout error detected.
