Why does my generated code have additional parameters when I am using Multi-Instance Capable Code in Stateflow Coder 5.0 (R13) or later?
显示 更早的评论
When I generate code from a Stateflow chart, some functions contain errors. The resulting code is not the same as it was in Stateflow Coder 4.1 (R12.1). The number of parameters passed to a function is not the same as when it has been declared.
For example, assume a function is declared with 3 parameters. When I call it, the code passes 5 parameters. The last two parameters are a repetition of the previous two.
Assume the declaration is:
void accessory_socket_f(SFaccessory_socket_fInstanceStruct *chartInstance,
SFaccessory_socket_fInputDataStruct
*chartInputData,SFaccessory_socket_fOutputDataStruct *chartOutputData)
With Stateflow Coder 4.1 (R12.1), the following code is produced:
accessory_socket_f(chartInstance, chartInputData, chartOutputData);
With Stateflow Coder 5.0 (R13), the following code is produced:
accessory_socket_f(chartInstance,chartInputData, chartOutputData,
chartInputData, chartOutputData);
This causes compilation errors.

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:
This has been verified as a bug in Stateflow Coder 5.0 (R13) and later in the way that the coder handles Multi-Instance Capable Code.
There are currently no known workarounds.
