Return structures in c function

Question

I am trying to return structfrom a function. It looks like this.

struct read(struct returnera returnDuo, struct vara varuArray[]) { 
     char varunr[LISTNUMBER], varunamn[LISTNUMBER];
     FILE *varuLista;
     varuLista = fopen(returnDuo.filnamn, "r");
     if(varuLista!=NULL) {
         while(fscanf(varuLista,"%s\t%s\t%d\n",varunr, varunamn, 
                      &varuArray[returnDuo.antalVaror].lagerSaldo) == 3){ 
            strncpy(varuArray[returnDuo.antalVaror].varuNr,varunr,5);
            strncpy(varuArray[returnDuo.antalVaror].varuNamn,varunamn,30);
            returnDuo.antalVaror++;
        } 
        printf("Filen är laddad..\n"); 
        kommaVidare();
     }
     else {
        printf("Filen hittades inte, skapar en tom fil"); kommaVidare();
     }
     fclose(varuLista);
     return returnDuo;
 }

I try to return the contents to a structure returnDuo, but I get an error: “Expected identifier or“ (“”. If I use a function void, it works as expected without returning anything, but I can’t figure out how to return this one struct.

This is how I set up the structures.

struct vara {
    char varuNr[5];
    char varuNamn[50];
    int lagerSaldo;
};

struct returnera {
    int antalVaror;
    char filnamn[LISTNUMBER];
};

And how do I configure them mostly.

struct vara varuArray[SIZE];

struct returnera returnDuo = {0,"0"};

I am happy to accept any advice on how to make this work ...

Answer 1

he should be

struct returnera read(struct returnera returnDuo, struct vara varuArray[])

not

struct read(struct returnera returnDuo, struct vara varuArray[])
