Using struct in function

[ClaudioBaldo]

I am trying to pass a STRUCT type to a FUNCTION for a legato API, following this topic below but I get a compile error:

In legato 19.02 api is not supporting more than 2 string

Hi legato, i am facing the issue in legato api struct . please check the below .api************************************************* STRUCT ARRAY { string Array1[10]; string Array2[10]; string Array3[10]; string Array4[10]; string Array5[10]; }; FUNCTION arraySend ( ARRAY asd ); log******** Apr 16 18:23:14 swi-mdm9x28-wp user.info Legato: INFO | canDBC[20710]/canDBCComponent T=canDBC | main.c PeriodicCanDataHdlr() 104 | PeriodicCanDataHdlr Apr 16 18:23:14 swi-mdm9x28-wp user.e…

void offlineData_arraySend

so it seems there is a conflict for the data type, I have seen comments about the STRUCT not to be supported, I have previously used the handlers, but I would just like to confirm that these are not supported before doing it for this case as well…

you can see here:

Syntax - Legato Docs

there is STRUCT

[ClaudioBaldo]

this doesn`t mention how to, or if is possible, to pass a struct to a FUNCTION of the API

[jyijyi]

you can try the sample code here:

In legato 19.02 api is not supporting more than 2 string

how about making the API file like this? STRUCT ARRAY123 { string Array1[10]; int32 port1; string Array2[10]; int32 port2; string Array3[10]; int32 port3; string Array4[10]; int32 port4; string Array5[10]; int32 port5; }; FUNCTION arraySend ( ARRAY123 asd IN ); It is working on my side with vscode leaf swi-wp76_4.7.0. You can use my code: IPC_step1.rar (2.4 KB)

as I just mentioned in the first message, this will not compile as it will detect a conflict of definitions.
please see the initial post I made

[jyijyi]

did you see problem in swi-wp76_4.7.0? ( as mentioned in the link)

[ClaudioBaldo]

I am compiling for wp77xx

[jyijyi]

you can download the swi-wp76_4.7.0 (legato 20.4.0) easily, this can confirm if issue only happen to your leaf package version or legato version

Or you can try in swi-wp77_4.2.0 which also uses legato 20.4.0
