I wrote a program consist of one ASM file and one C file. I compiled
them with masm613
and msvc152. But I can't call the function in the C file from my ASM
file.
The expected output is:
hello1
hello2
testing...
hello3
0080

But the output is:
hello1
hello2
[some kind of messy code]
hello3
0090

It seemed that I called some other unknown address when I called
_DriverInit. Why?
What's wrong with my sourcecode or makefile? And why my offset
cshd_dioa is 0090h not 0080h ?Following I list my sourcecode and
makefile. Thank you very much.
