windows - How to obtain the handle to keyboard device? -


i trying hook keyboard isr, can't open device because createfile returns 0000007bh error_invalid_name. have done incorrectly?

invoke definedosdevice,[raw],filename1,devicename lea     rcx,[filename2] invoke  createfilea,rcx,generic_all,file_share_write or  file_share_read,0,3,0,0 ret  section '.data' data writeable readable  devicename      db '\\device\\keyboardclass0',0 filename1       db 'keyboard',0 filename2       db '\\.\keyboard',0 raw             dq      1

this flat assembler syntax, should pass devicename without escaping slashes:

devicename      db '\device\keyboardclass0',0

there's tutorial source code in c how access keyboard device in windows. might find interesting.

translating assembly, you'll want like

include 'include\win64ax.inc'  .code   start:   invoke definedosdevice, 1, kbdfilename, kbddevicename   mov rcx, kbdpath   invoke  createfile, rcx, generic_write, 0, 0, open_existing, 0, 0   mov [hkbd], rax   ;. . .   invoke exitprocess, 0  .end start   .data  kbddevicename  db '\device\keyboardclass0',0 kbdfilename    db 'kbd',0 kbdpath        db '\\.\kbd',0 hkbd           dq ?
