IDL files are always preprocessed using the C preprocessor.
-Pretty much everything in an interface (the interface itself, functions,
-parameters) can have attributes (or properties whatever name you give them).
-Attributes always prepend the element they apply to and are surrounded
-by square brackets ([]). Multiple attributes are separated by comma's;

=head2 CONFORMANT ARRAYS
A conformant array is one with that ends in [*] or []. The strange
-things about conformant arrays are that they can only appear as the last
-element of a structure (unless there is a pointer to the conformant array,
-of course) and the array size appears before the structure itself on the wire.
+things about conformant arrays are that they can only appear as the last
+element of a structure (unless there is a pointer to the conformant array,
+of course) and the array size appears before the structure itself on the wire.
So, in this example:
typedef struct {
long abc;
- long count;
+ long count;
long foo;
[size_is(count)] long s[*];
} Struct1;
typedef struct {
long abc;
- long count;
+ long count;
long foo;
long s[1];
} Struct1;
pidl takes a different approach, and writes it like this:
- typedef struct {
+ typedef struct {
long abc;
- long count;
+ long count;
long foo;
long *s;
} Struct1;
typedef struct {
long abc;
- long count;
+ long count;
long foo;
[size_is(count)] long *s;
} Struct1;
A fixed array looks like this:
- typedef struct {
- long s[10];
- } Struct1;
+ typedef struct {
+ long s[10];
+ } Struct1;
The NDR representation looks just like 10 separate long
declarations. The array size is not encoded on the wire.
pidl also supports "inline" arrays, which are not part of the IDL/NDR
standard. These are declared like this:
- typedef struct {
- uint32 foo;
- uint32 count;
- uint32 bar;
- long s[count];
- } Struct1;
+ typedef struct {
+ uint32 foo;
+ uint32 count;
+ uint32 bar;
+ long s[count];
+ } Struct1;
This appears like this:
[foo] [count] [bar] [s...]
Fixed arrays are an extension added to support some of the strange
