ssSetLocalErrorStatus

Report an error in a thread-safe manner

Syntax

void ssSetLocalErrorStatus(SimStruct *S, const char_T *msg)

Arguments

S

SimStruct representing an S-Function block or a Simulink®model.

msg

Error message.

Description

Use this function for thread-safe reporting of errors that occur in your S-function. For example:

ssSetLocalErrorStatus(S, "error message"); return;

Note

The error message character vector must be in persistent memory; it cannot be a local variable. If you usesprintfto 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)); ssSetLocalErrorStatus(S,msg);

This function causes the Simulink engine to stop and display the specified error message, therefore it is followed by areturnstatement. 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 for applications to run on R2019a or later for thread safety. For earlier releases, usessSetErrorStatusinstead.
