我試圖初始化一個WIN32_FIND_DATA結構體,該結構體用於存儲有關FindFirstFile和FindNextFile窗口函數的文件信息。問題是我無法弄清楚如何在yasm中初始化一個stuct。 這裏是我的代碼:初始化yasm x86程序集中的一個結構體
struc FILETIME
.dwLowDateTime resd 1
.dwHighDateTime resd 1
endstruc
struc WIN32_FIND_DATA
.dwFileAttributes resd 1
.ftCreationTime resb FILETIME_size
.ftLastAccessTime resb FILETIME_size
.ftLastWriteTime resb FILETIME_size
.nFileSizeHigh resd 1
.nFileSizeLow resd 1
.dwReserved0 resd 1
.dwReserved1 resd 1
.cFileName resb 260
.cAlternateFileName resb 14
endstruc
[bits 32]
section .text
extern _exit
global _main
_main:
push 0
call _exit
ret
section .data
dataWin32:
istruc WIN32_FIND_DATA
at a, dd 0
at b, db 0
at c, db 0
at d, db 0
at e, dd 0
at f, dd 0
at g, dd 0
at h, dd 0
at i, db 0
a
iend
我得到的錯誤是:
testStruct.asm:38: error: undefined symbol `b' (first use)
testStruct.asm:38: error: (Each undefined symbol is reported only once.)
testStruct.asm:39: error: undefined symbol `c' (first use)
testStruct.asm:40: error: undefined symbol `d' (first use)
testStruct.asm:41: error: undefined symbol `e' (first use)
testStruct.asm:42: error: undefined symbol `f' (first use)
testStruct.asm:43: error: undefined symbol `g' (first use)
testStruct.asm:44: error: undefined symbol `h' (first use)
testStruct.asm:45: error: undefined symbol `i' (first use)
你期望'a,''b'等等能做什麼?結構中沒有這個名字的字段! –
你的意思是我應該有'而','.dwFileAttributes'? –
@WeeBey:彙編程序無法猜測你想要什麼。你必須使用正確的標識符。你必須完全限定它們:'WIN32_FIND_DATA.dwFileAttributes'等。 –
