如何忽略回车键 NASM win32

Question

我需要忽略输入上的回车，以进一步将输入字符串与其他字符串进行比较。

代码输入和输出的波纹管片段

;get output handle
    push dword STD_OUTPUT_HANDLE
    call GetStdHandle
    mov [hstdout],eax
    mov eax, 1000h


    ;get input handle
    push dword STD_INPUT_HANDLE
    call GetStdHandle
    mov [hstdin],eax

    ;Read
    push 0
    push actlen2 ;Pointer to a DWORD for number of characters read to be returned
    push 11
    push string
    push dword [hstdin]
    call ReadConsoleA

    ;Write
    push 0
    push actlen
    push 11
    push string
    push dword [hstdout]
    call WriteFile

字符串有换行符

我想通了
我刚刚编写了从字符串

中删除 0x0d 和 0x0a 的代码

    mov ecx,11; str len(and num of loop iterations)
    mov eax,string
    jmp ignore_enter
change_byte:
    mov bl,0
    mov byte[eax+ecx],bl;change byte to 0
ignore_enter:
    cmp byte[eax+ecx], 0x0a; compare ecx byte of string with 0x0a
    je change_byte; if equal change_byte
    cmp byte[eax+ecx], 0x0D; compare ecx byte of string with 0x0d
    je change_byte; if equal change_byte
    loop ignore_enter
