enum stuff get lost

[ajay]

Hi All,
I get lost in enum stuff.
can anyone help me out from this puzzle.
i'm not able to get the values which i set.
see the following piece of code.


/** typedef.h ****/

/***** I have an enum ******/

enum RequestParameter{
request_IMSI = 0,
request_AuthenticationSet = 1,
request_SubscriberData = 2,
request_CUG_Information = 3,
request_Ki = 4
};

/*** now i have to create an arry of above enum of size 2 ******/
typedef RequestParameter RequestParameters[2];


/**** getSet.c ******/

/*** I wrote method to get and set this enum array ***/
RequestParameters reqParams;

void setReqParams(RequestParameters* in)
{
reqParams = in;
}

bool getReqParams(RequestParameters* out)
{
out = reqParams;
}

/**** main.c *****/
/***** now i use get set methods *****/

/*** here i set the value ***/

RequestParameters reqParams;
reqParams[0] = request_IMSI;
setReqParams(&reqParams);


/**** here i get the value ******/
RequestParameters reqParams;
getReqParams(&reqParams));

printf("reqParam = %d" , reqParam[0] );
/** i'm not able to get the values which i set printed value is garbage ***/

if ( reqParams[0] == request_IMSI )
{
......
}
else if ( reqParams[0] == request_AuthenticationSet )
{
.....
}

......
...

Should be

typedef enum RequestParameter RequestParameters[2];

but typedefing arrays is rarely useful.

/**** getSet.c ******/

/*** I wrote method to get and set this enum array ***/
RequestParameters reqParams;

void setReqParams(RequestParameters* in)

'RequestParameters' is an array type that decays in a pointer type because it
is a parameter. Are you sure you want a pointer to a pointer here?

{
reqParams = in;

What is reqParams ?

}

bool getReqParams(RequestParameters* out)
{
out = reqParams;

out = reqParams;

What is reqParams ?
Modifying a parameter is often the sign of a design error. Do you really want
to do that?

}

/**** main.c *****/
/***** now i use get set methods *****/

/*** here i set the value ***/

RequestParameters reqParams;
reqParams[0] = request_IMSI;

You can't do that outside a function.

setReqParams(&reqParams);

It's hard to understand the purpose of this function.

/**** here i get the value ******/
RequestParameters reqParams;
getReqParams(&reqParams));

It's hard to understand the purpose of this function.

printf("reqParam = %d" , reqParam[0] );
/** i'm not able to get the values which i set printed value is garbage
***/

if ( reqParams[0] == request_IMSI )
{
.....
}
else if ( reqParams[0] == request_AuthenticationSet )
{
....
}

You seem completely confused. I think you should try to explain what you want
to do exactly, and we will try to help you to implement it if it makes sense.

Tx ED for ur time.I solved it anyhow.

^^^^^^^^^
This is reqParams.

RequestParams is not a parameter. RequestParams is, as you have
correctly said, an array type. But the parameter, named in, is a
pointer to this array type.

What is reqParams ?

See above.

I believe he's trying to modify what the parameter points at. Of
course, he can't do that, since it is an array.
