VC6.0 中的__asm语句

VC6.0 中的__asm语句

就几句E文`大家都看的懂吧`

C/C++ Language Reference

__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.

Note   Visual C++ does not support the Standard C++ asm keyword.

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

__asm mov eax, 01h      // Separate __asm lines
__asm int 10h

// Multiple __asm statements on a line
__asm mov eax, 01h   __asm int 10h
