Detailed Description

Definitions of IDP, LDR, PLUGIN module interfaces.

This file also contains:

• functions to load files into the database
• functions to generate output files
• high level functions to work with the database (open, save, close)

The LDR interface consists of one structure: loader_t
The IDP interface consists of one structure: processor_t
The PLUGIN interface consists of one structure: plugin_t

Modules can't use standard FILE* functions. They must use functions from <fpro.h>

Modules can't use standard memory allocation functions. They must use functions from <pro.h>

The exported entry #1 in the module should point to the the appropriate structure. (loader_t for LDR module, for example)

Macro Definition Documentation

ACCEPT_FIRST

#define ACCEPT_FIRST   0x8000

Specify that a file format should be place first in "load file" dialog box.

See loader_t::accept_file

FILEREG_PATCHABLE

#define FILEREG_PATCHABLE   1

means that the input file may be patched (i.e.

no compression, no iterated data, etc)

FILEREG_NOTPATCHABLE

#define FILEREG_NOTPATCHABLE   0

the data is kept in some encoded form in the file.

Typedef Documentation

importer_t

typedef int idaapi importer_t(linput_t *li, impinfo_t *ii)

Callback for checking dll module - passed to import_module().

Parameters

li	pointer to input file
ii	import info. If the function finds that ii.dllname does not match the module name passed to import_module(), it returns 0. Otherwise it calls ii.func for each exported entry. If ii.dllname==nullptr then ii.func will be called with num==0 and name==dllname.

Return values

0	dllname doesn't match, import_module() should continue
1	ok

Enumeration Type Documentation

ofile_type_t

enum ofile_type_t

Output file types.

Enumerator
OFILE_MAP	MAP file.
OFILE_EXE	Executable file.
OFILE_IDC	IDC file.
OFILE_LST	Disassembly listing.
OFILE_ASM	Assembly.
OFILE_DIF	Difference.

Function Documentation

loader_failure()

NORETURN void loader_failure ( const char *  format = nullptr,   ...  )

inline

Display a message about a loader failure and stop the loading process.

The kernel will destroy the database. If format == nullptr, no message will be displayed This function does not return (it longjumps)! It may be called only from loader_t::load_file

get_loader_name_from_dll()

idaman char *ida_export get_loader_name_from_dll

(

char *

dllname

)

Get name of loader from its DLL file (for example, for PE files we will get "PE").

This function modifies the original string and returns a pointer into it. NB: if the file extension is a registered extlang extension (e.g. py or idc) the extension is retained

get_loader_name()

idaman ssize_t ida_export get_loader_name	(	char *	buf,
		size_t	bufsize
	)

Get name of loader used to load the input file into the database.

If no external loader was used, returns -1. Otherwise copies the loader file name without the extension in the buf and returns its length (for example, for PE files we will get "PE"). For scripted loaders, the file extension is retained.

load_binary_file()

idaman bool ida_export load_binary_file	(	const char *	filename,
		linput_t *	li,
		ushort	_neflags,
		qoff64_t	fileoff,
		ea_t	basepara,
		ea_t	binoff,
		uint64	nbytes
	)

Load a binary file into the database.

This function usually is called from ui.

Parameters

filename	the name of input file as is (if the input file is from library, then this is the name from the library)
li	loader input source
_neflags	Load file flags. For the first file, the flag NEF_FIRST must be set.
fileoff	Offset in the input file
basepara	Load address in paragraphs
binoff	Load offset (load_address=(basepara<<4)+binoff)
nbytes	Number of bytes to load from the file. 0: up to the end of the file

If nbytes is bigger than the number of bytes rest, the kernel will load as much as possible

Return values

true	ok
false	failed (couldn't open the file)

load_nonbinary_file()

idaman bool ida_export load_nonbinary_file	(	const char *	filename,
		linput_t *	li,
		const char *	sysdlldir,
		ushort	_neflags,
		load_info_t *	loader
	)

Load a non-binary file into the database.

This function usually is called from ui.

Parameters

filename	the name of input file as is (if the input file is from library, then this is the name from the library)
li	loader input source
sysdlldir	a directory with system dlls. Pass "." if unknown.
_neflags	Load file flags. For the first file the flag NEF_FIRST must be set.
loader	pointer to load_info_t structure. If the current IDP module has processor_t::loader != nullptr then this argument is ignored.

Returns

success

process_archive()

idaman int ida_export process_archive	(	qstring *	temp_file,

		const load_info_t *	loader,
		qstring *	errbuf = nullptr
	)

Calls loader_t::process_archive() For parameters and return value description look at loader_t::process_archive().

Additional parameter 'loader' is a pointer to load_info_t structure.

gen_file()

idaman int ida_export gen_file	(	ofile_type_t	otype,

Parameters

otype	type of output file.
fp	the output file handle
ea1	start address. For some file types this argument is ignored
ea2	end address. For some file types this argument is ignored as usual in ida, the end address of the range is not included
flags	Generate file flags

For OFILE_EXE:

Return values

0	can't generate exe file
1	ok

For other file types:

Returns

number of the generated lines. -1 if an error occurred

build_snapshot_tree()

idaman bool ida_export build_snapshot_tree

(

snapshot_t *

root

)

Build the snapshot tree.

Parameters

root	snapshot root that will contain the snapshot tree elements.

Returns

success

update_snapshot_attributes()

idaman bool ida_export update_snapshot_attributes	(	const char *	filename,
		const snapshot_t *	root,
		const snapshot_t *	attr,
		int	uf
	)

Update the snapshot attributes.

Note

only the snapshot description can be updated.

Parameters

filename	snapshot file name or nullptr for the current database
root	snapshot root (returned from build_snapshot_tree())
attr	snapshot instance containing the updated attributes
uf	Snapshot update flags

Returns

success

visit_snapshot_tree()

idaman int ida_export visit_snapshot_tree	(	snapshot_t *	root,
		int(idaapi *)(snapshot_t *ss, void *ud)	callback,
		void *	ud = nullptr
	)

Visit the snapshot tree.

Parameters

root	snapshot root to start the enumeration from
callback	callback called for each child. return 0 to continue enumeration and non-zero to abort enumeration
ud	user data. will be passed back to the callback

Returns

true-ok, false-failed

save_database()

idaman bool ida_export save_database	(	const char *	outfile,
		uint32	flags,
		const snapshot_t *	root = nullptr,
		const snapshot_t *	attr = nullptr
	)

Save current database using a new file name.

Parameters

outfile	output database file name
flags	Database flags
root	optional: snapshot tree root.
attr	optional: snapshot attributes

Note

when both root and attr are not nullptr then the snapshot attributes will be updated, otherwise the snapshot attributes will be inherited from the current database.

Returns

success
