__asm (Windows CE 5.0)

Send Feedback

The __asm keyword invokes the inline assembler on the declarations that follow it. __asm may not be used alone. It must be followed by an assembly instruction, a group of instructions enclosed in braces, or an empty pair of braces.

__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.

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

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

Remarks

The SH-4 microprocessor treats the __asm keyword as a function call. This imposes certain restrictions on the use of __asm in SH-4 inline assembly. For more information, see Limitations of the __asm Keyword in SH-4 Inline Assembly.
