Marvin, thanks.
It seems I have to keep my manual padding!

Marvin, thanks.
What i'm doing is similar to your guessing.
I use syscall.Syscall to call win32 api, and encounter some padding issues.
I have resolve my problems by mannual padding days ago, but I want to know
if there is a more graceful way to finish that.
One of the Apis is:
DWORD WINAPI F

This smells like the XY problem. What are you actually trying to do and
how have to tried to do it (actual code, not simplified analogues)?

peterGo, thanks.
How can i use this kind of Go in windows? my machine is 64bit also. If I
download the amd64 Go, the pointer size will be 8 bytes.
My real issue is , when I call win32 api, uint64 type in the struct of
win32 is aligned to 8 bytes.
I have to pad the go struct by manual to make i
xjdrew,
The Go Playground is (GOOS/GOARCH) nacl/amd64p32 which is a 64 bit
architecture, where the address space is limited to a 4GB (32 bit) window.
It has 8 byte (64 bit) data structure alignment.
linux/386 and windows/386 are 32 bit architectures, where the address space
is 4GB (32 bit). Th
