Topic created on: September 4, 2008 02:33 CDT by Piotr .


I've involved in some IDA plugin work lately. And i'm actually having some problems with imported data recognition.

For example:


.idata:0040304C ; void __stdcall ExitProcess(UINT uExitCode)
.idata:0040304C                 extrn __imp_ExitProcess:dword ; DATA XREF: ExitProcessr


Basically my question is, is there any special flag which marks the 0x0040304c location as something like "imported api addr" or so? Thanks.

If I'm not wrong, Chris Eagle's IDA Pro Book lists some IDC script code which is capable of exporting a DLL's exported names to a file. Maybe similar code can be applied to imports. idabook.com

edit:

maybe you can use "is_spec_segm(uchar seg_type)" with seg_type being SEG_XTRN (segment.hpp) ?


void idaapi run(int arg)
{
segment_t *seg;

if( (seg = getseg(get_screen_ea())) != 0 )
msg("xtrn: %d\n", (seg->type == SEG_XTRN) );
}

Heyo dennis, yeah it seems the getseg solution is working i hope it will stay that way. thanks man :)

Yes, IDA uses segment type SEG_XTRN and class name "XTRN" to represent arrays of imported addresses.

Thank you both. The thread should be now closed, if there is any such option here :-)

if we load the file with option "Make imports segment" unchecked,then SEG_XTRN will failed.
I found isLoaded in the headers.It seems this api will works.


// Does the specified address have a byte value (is initialized?)

idaman bool ida_export isLoaded(ea_t ea);
