Report an error
void ssSetErrorStatus(SimStruct *S, const char_T *msg)
SSimStruct representing an S-Function block or a Simulink® model.
msgError message.
Use this function to report errors that occur in your S-function in a single-threaded application. For example:
ssSetErrorStatus(S, "error message"); return;
Note
The error message character vector must be in persistent memory; it cannot be
a local variable. If you use sprintf to format the error
message, you must allocate memory for the message. For example:
static char msg[35]; sprintf(msg,"Expected number of parameters: %d",ssGetNumSFcnParams(S)); ssSetErrorStatus(S,msg);
This function causes the Simulink engine to stop and display the specified error message, therefore it
is followed by a return statement. The function does not generate
an exception. Thus you can use it in your S-function to avoid creating exceptions
when reporting errors.
Use this function to report errors in single-threaded applications or applications
that must run on releases before R2019a. For multi-threaded applications, use
ssSetLocalErrorStatus instead.
