Useful + for debugging pidl. + + + + --dump-ndr-tree + + Tell pidl to dump the internal NDR information tree it generated + from the IDL file to disk. Useful for debugging pidl. + + + + + + + IDL SYNTAX + + 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; arguments to attributes are + specified between parentheses. + + See the section COMPATIBILITY for the list of attributes that + pidl supports. + + C-style comments can be used. + + + CONFORMANT ARRAYS + + +A conformant array is one with that ends in [*] or []. The strange +things about conformant arrays are: + + + + they can only appear as the last element of a structure + the array size appears before the structure itself on the wire. + + + + So, in this example: + + + + typedef struct { + long abc; + long count; + long foo; + [size_is(count)] long s[*]; + } Struct1; + + + +it appears like this: + + + +[size_is] [abc] [count] [foo] [s...] + + + +the first [size_is] field is the allocation size of the array, and +occurs before the array elements and even before the structure +alignment. + + + +Note that size_is() can refer to a constant, but that doesn't change +the wire representation. It does not make the array a fixed array. + + + +midl.exe would write the above array as the following C header: + + + + typedef struct { + long abc; + long count; + long foo; + long s[1]; + } Struct1; + + + +pidl takes a different approach, and writes it like this: + + + + typedef struct { + long abc; + long count; + long foo; + long *s; + } Struct1; + + + + + + VARYING ARRAYS + + +A varying array looks like this: + + + + typedef struct { + long abc; + long count; + long foo; + [size_is(count)] long *s; + } Struct1; + + + +This will look like this on the wire: + + + +[abc] [count] [foo] [PTR_s] [count] [s...] + + + + + + FIXED ARRAYS + + +A fixed array looks like this: + + + + 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; + + + +This appears like this: + + + +[foo] [count] [bar] [s...] + + + +Fixed arrays are an extension added to support some of the strange +embedded structures in security descriptors and spoolss. + + + + +This section is by no means complete. See the OpenGroup and MSDN + documentation for additional information. + + + + COMPATIBILITY WITH MIDL + + + Missing features in pidl + + The following MIDL features are not (yet) implemented in pidl + or are implemented with an incompatible interface: + + + + Asynchronous communication + Typelibs (.tlb files) + Datagram support (ncadg_*) + + + + + Supported properties (attributes is the MIDL term) + + + in, out, ref, length_is, switch_is, size_is, uuid, case, default, string, unique, ptr, pointer_default, v1_enum, object, helpstring, range, local, call_as, endpoint, switch_type, progid, coclass, iid_is. + + + + + + PIDL Specific properties + + + public + +The [public] property on a structure or union is a pidl extension that +forces the generated pull/push functions to be non-static. This allows +you to declare types that can be used between modules. If you don't +specify [public] then pull/push functions for other than top-level +functions are declared static. + + + + noprint + +The [noprint] property is a pidl extension that allows you to specify +that pidl should not generate a ndr_print_*() function for that +structure or union. This is used when you wish to define your own +print function that prints a structure in a nicer manner. A good +example is the use of [noprint] on dom_sid, which allows the +pretty-printing of SIDs. + + + + value + +The [value(expression)] property is a pidl extension that allows you +to specify the value of a field when it is put on the wire. This +allows fields that always have a well-known value to be automatically +filled in, thus making the API more programmer friendly. The +expression can be any C expression. + + + + relative + +The [relative] property can be supplied on a pointer. When it is used +it declares the pointer as a spoolss style "relative" pointer, which +means it appears on the wire as an offset within the current +encapsulating structure. This is not part of normal IDL/NDR, but it is +a very useful extension as it avoids the manual encoding of many +complex structures. + + + + subcontext(length) + + Specifies that a size of length + bytes should be read, followed by a blob of that size, + which will be parsed as NDR. + + + + flag + + Specify boolean options, mostly used for + low-level NDR options. Several options + can be specified using the | character. + Note that flags are inherited by substructures! + + + + nodiscriminant + +The [nodiscriminant] property on a union means that the usual uint16 +discriminent field at the start of the union on the wire is +omitted. This is not normally allowed in IDL/NDR, but is used for some +spoolss structures. + + + + charset(name) + + Specify that the array or string uses the specified + charset. If this attribute is specified, pidl will + take care of converting the character data from this format + to the host format. Commonly used values are UCS2, DOS and UTF8. + + + + + + + Unsupported MIDL properties + +aggregatable, appobject, async_uuid, bindable, control, cpp_quote, defaultbind, defaultcollelem, defaultvalue, defaultvtable, dispinterface, displaybind, dual, entry, first_is, helpcontext, helpfile, helpstringcontext, helpstringdll, hidden, idl_module, idl_quote, id, immediatebind, importlib, import, include, includelib, last_is, lcid, licensed, max_is, module, ms_union, no_injected_text, nonbrowsable, noncreatable, nonextensible, odl, oleautomation, optional, pragma, propget, propputref, propput, readonly, requestedit, restricted, retval, source, transmit_as, uidefault, usesgetlasterror, vararg, vi_progid, wire_marshal. + + + + + + + ETHEREAL CONFORMANCE FILES + + +Pidl needs additional data for ethereal output. This data is read from +so-called conformance files. This section describes the format of these +files. + + +Conformance files are simple text files with a single command on each line. +Empty lines and lines starting with a '#' character are ignored. +Arguments to commands are seperated by spaces. + + + +The following commands are currently supported: + + + + + + TYPE name dissector ft_type base_type mask valsstring alignment + Register new data type with specified name, what dissector function to call and what properties to give header fields for elements of this type. + + + + NOEMIT type + + Suppress emitting a dissect_type function for the specified type + + + + + PARAM_VALUE type param + + Set parameter to specify to dissector function for given type. + + + + + HF_FIELD hf title filter ft_type base_type valsstring mask description + + Generate a custom header field with specified properties. + + + + + HF_RENAME old_hf_name new_hf_name + + Force the use of new_hf_name when the parser generator was going to + use old_hf_name. + + + + This can be used in conjunction with HF_FIELD in order to make more then + one element use the same filter name. + + + + + + STRIP_PREFIX prefix + + Remove the specified prefix from all function names (if present). + + + + + PROTOCOL longname shortname filtername + + Change the short-, long- and filter-name for the current interface in + Ethereal. + + + + + FIELD_DESCRIPTION field desc + Change description for the specified header field. `field' is the hf name of the field. + + + + + IMPORT dissector code... + + Code to insert when generating the specified dissector. @HF@ and + @PARAM@ will be substituted. + + + + + + + + + EXAMPLES + + + # Generating an ethereal parser + $ ./pidl --eth-parser -- atsvc.idl + + # Generating a TDR parser + $ ./pidl --tdr-parser --tdr-header --header -- regf.idl + + + + + + VERSION + + This man page is correct for version 4.0 of the Samba suite. + + + + SEE ALSO + + Field Attributes [Remote Procedure Call], Ethereal Wiki on DCE/RPC. + + + + + AUTHOR + + pidl was written by Andrew Tridgell, Stefan Metzmacher, Tim + Potter and Jelmer Vernooij. + + This manpage was written by Jelmer Vernooij, partially based on the original pidl README by Andrew Tridgell. + + + + diff --git a/tools/pidl/pm_to_blib b/tools/pidl/pm_to_blib new file mode 100644 index 0000000000..e69de29bb2 diff --git a/tools/pidl/ref_notes.txt b/tools/pidl/ref_notes.txt new file mode 100644 index 0000000000..00f44fddb7 --- /dev/null +++ b/tools/pidl/ref_notes.txt @@ -0,0 +1,220 @@ +some experiments with ref ptrs + + + + typedef struct { + short x;
