看完下面的代码(来自MSDN),你就明白了是什么意思,而且你的英语也会提高那么一点点。其实他就是一个汇编语言指令。

__asm
Microsoft Specific

__asm

assembly-language-instruction

__asm
{
assembly-language-instructions
}

If used without braces, the __asm keyword means that the rest of the line is an assembly-language statement. If used with braces, it means that each line between the braces is an assembly-language statement. For compatibility with previous versions, _asm is a synonym for __asm.

Since the __asm keyword is a statement separator, you can put assembly instructions on the same line.

For related information, see Assembler (Inline) Topics.

Note Microsoft C++ does not support the AT&T C++ asm keyword.

END Microsoft Specific

Example

// Example of the __asm keyword
__asm // __asm block
{
mov eax, 01h
int 10h
}

__asm mov eax, 01h /
