Re: Enumerated types

...

Is it possible to specify the value of an enumerated type? I was trying

to

...

port a C header file which did something like this:

typedef enum hello_everybody {
    hello_error = -1,
    hello_first =  0,
    hello_second,
    hello_third

Can this be done with GPC?

I am noot quite sure what you whant to do here. Under Pascal you can write:

type Hello_Everybody = (Hello_error, Hello_first, Hello_second, Hello_third);

and then use the ORD function to get their numerical value. ORD(Hello_Error) would be 0, ORD(Hello_First) 1 and so on. This would be an enumerated type.

The other option would be a record (similar to a C struct):

type Hello_Everybody = record Hello_Error, Hello_First, Hello_Second, Hello_Third : integer; end;

In this case you could assign any integer value you like to any of the records field, while in the case of enumeration types the ORD-value is given by the order of definition.

Hope that helps
