# \_KERNEL32\_41(3w)

(KERNEL32.41)

## NAME

\_KERNEL32\_41 - (KERNEL32.41)

## SYNOPSIS

**LPVOID \_KERNEL32\_41**\
 **(**\
\
 	**LPBYTE thunk,**\
\
 	**LPCSTR thkbuf,**\
\
 	**DWORD len,**\
\
 	**LPCSTR dll16,**\
\
 	**LPCSTR dll32**\
 **);**

## DESCRIPTION

A thunk setup routine. Expects a pointer to a preinitialized thunkbuffer in the first argument looking like:\
 00\..03:		unknown	(pointer, check \_41, \_43, \_46) 04: EB1E		jmp +0x20\

06\..23:		unknown (space for replacement code, check .90).

## 24

\>E800000000		call offset 29 29:\>58			pop eax		   ( target of call ) 2A: 2D25000000		sub eax,0x00000025 ( now points to offset 4 ) 2F: BAxxxxxxxx		mov edx,xxxxxxxx 34: 68yyyyyyyy		push KERNEL32.90 39: C3			ret.

## 3A

EB1E		jmp +0x20 3E ... 59:	unknown (space for replacement code?) 5A: E8xxxxxxxx		call \<32bitoffset xxxxxxxx\> 5F: 5A			pop edx 60: 81EA25xxxxxx	sub edx, 0x25xxxxxx 66: 52			push edx 67: 68xxxxxxxx		push xxxxxxxx 6C: 68yyyyyyyy		push KERNEL32.89 71: C3			ret 72: end? This function checks if the code is there, and replaces the yyyyyyyy entries by the functionpointers. The thunkbuf looks like:.

## 00

DWORD	length		? don't know exactly 04: SEGPTR	ptr		? where does it point to? The segpointer ptr is written into the first DWORD of 'thunk'. \[Ok probably\].
