typedef stuct problem in C

Question

I am facing a weird problem I have defined I a structure in a C header file:

typedef struct iRecActive{

    char iRecSID[32];
    unsigned char RecStatus;
             


        

Answer 1

I tried to find solution for similar problem but I didn't find it on stack. I leave here answer for other people, to save their time:

Because it is C, you cannot create your variables where you want. They must be created at the beginning of statement. So this is correct:

if(true) {
   iRecActive_t myRecActive;
   //calculations
   Mutex_Lock(somemutext);
   variable = 14;

And this is incorrect:

if(true) {
   //calculations
   Mutex_Lock(somemutext);
   variable = 14;
   iRecActive_t myRecActive;

In last example you get error message: illegal use of this type as expression or some other similar, very useful errors.

Proper question is here, but it was marked as duplication (it is not!): typedef stuct problem in C (illegal use of this type as an expression)

Answer 2

change iRecAcitve_t to iRecActive_t.
