It seems that there is a problem with (u)char type, or I misunderstand it.
local _1_=esc(?"\x01",?"\")
local t=dll.create_struct("i o c c c c",1,1,1,1,1,1)
win.debug(t[1],t[2],t[3],t[4],t[5],t[6])
The results is:
1 0x31310001 0x31313131 0x313131 0x3131 0x31
If neglecting the stack alignment problem (:is it correct name?), 1/0
is correctly assigned, i.e., 0x01/0x00, for integer and short types,
whereas is incorrectly assigned, i.e., their ascii values 0x31/0x30,
for char types. So, have to use _1_/"" instead with char types.
And, I can't still find a way to assign a literal string in struct.
