Well,i used this API like thin in .asm file:

.586p
locals
jumps
.Model Flat ,StdCall
o equ offset
extern DebugActiveProcessStop :PROC
bla...bla...bla...

no linking problems,nothing.I debugged the exe in Olly (v1.10) but i cannot see anywhere this API i declared.If i also make a call in the code of the exe,then an error during linkig appearz.I used tasm32.

Can anyone plz help?This happens also with other debugging APIs I may declare...
thankz
