Dll MASM32中的crt_printf和ExitProcess与lib crt\U printf、crt\U scanf、ExitProcess 环境路径为masm32v11r的Windows 7

在.asm文件中，我想调用crt_printf来打印（或者调用ExitProcess来结束主过程）。但是，我的代码是：

.386  
.model flat,stdcall  
option casemap:none  
includelib D:\masm32\lib\msvcrt.lib  
printf proto C:dword,:vararg  
scanf proto C:dword,:vararg

.DATA
print_int    DB "%d",0
print_char   DB "%c",0

PUSH    offset __temp13@_cal@main
PUSH    offset print_string
CALL    crt_printf
ADD     ESP,    8
PUSH    _realCock@main
PUSH    offset print_int
CALL    crt_printf
ADD     ESP,    8
PUSH    offset __temp14@_cal@main

我的通话程序如下：

.386  
.model flat,stdcall  
option casemap:none  
includelib D:\masm32\lib\msvcrt.lib  
printf proto C:dword,:vararg  
scanf proto C:dword,:vararg

.DATA
print_int    DB "%d",0
print_char   DB "%c",0

PUSH    offset __temp13@_cal@main
PUSH    offset print_string
CALL    crt_printf
ADD     ESP,    8
PUSH    _realCock@main
PUSH    offset print_int
CALL    crt_printf
ADD     ESP,    8
PUSH    offset __temp14@_cal@main

当我单击“全部构建”按钮时，会出现以下消息：

我已经和这样的错误斗争了24小时，谢谢

crt\u printf

是MASM32开发人员的一种特殊构造，用于将其与他们的宏

printf

区分开来。如果不包括

\masm32\macros\macros.asm

，则不需要此特殊功能：

.386
.model flat,stdcall

includelib \masm32\lib\msvcrt.lib
includelib \masm32\lib\kernel32.lib

printf proto C :dword, :vararg          ; msvcrt
ExitProcess proto STDCALL :DWORD        ; kernel32

.DATA
    fmt db "%s",10,0
    hello db "Hello world!",0

.CODE
main PROC
    push OFFSET hello
    push OFFSET fmt
    call printf
    add esp, (2 * 4)

    push 0
    call ExitProcess
main ENDP

END main

crt.

别名在

msvcrt.inc

中声明：

.386
.model flat,stdcall

include \masm32\include\msvcrt.inc

includelib \masm32\lib\msvcrt.lib
includelib \masm32\lib\kernel32.lib

printf proto C :dword, :vararg          ; msvcrt
ExitProcess proto STDCALL :DWORD        ; kernel32

.DATA
    fmt db "%s",10,0
    hello db "Hello world!",0

.CODE
main PROC
    push OFFSET hello
    push OFFSET fmt
    call crt_printf
    add esp, (2 * 4)

    push 0
    call ExitProcess
main ENDP

END main

include \masm32\include\masm32rt.inc

.DATA
    fmt db "%s",10,0
    hello db "Hello world!",0

.CODE
main PROC
    push OFFSET hello
    push OFFSET fmt
    call crt_printf
    add esp, (2 * 4)

    printf ("Hello again: %s\n",OFFSET hello);

    push 0
    call ExitProcess
main ENDP

END main

如果您想要全部声明和宏，那么就包括

masm32rt.inc

：

.386
.model flat,stdcall

include \masm32\include\msvcrt.inc

includelib \masm32\lib\msvcrt.lib
includelib \masm32\lib\kernel32.lib

printf proto C :dword, :vararg          ; msvcrt
ExitProcess proto STDCALL :DWORD        ; kernel32

.DATA
    fmt db "%s",10,0
    hello db "Hello world!",0

.CODE
main PROC
    push OFFSET hello
    push OFFSET fmt
    call crt_printf
    add esp, (2 * 4)

    push 0
    call ExitProcess
main ENDP

END main

include \masm32\include\masm32rt.inc

.DATA
    fmt db "%s",10,0
    hello db "Hello world!",0

.CODE
main PROC
    push OFFSET hello
    push OFFSET fmt
    call crt_printf
    add esp, (2 * 4)

    printf ("Hello again: %s\n",OFFSET hello);

    push 0
    call ExitProcess
main ENDP

END main
