''Part of'' KeywordsCategory

== Description ==

D allows the use of inline assembly language

== Example ==

{{{
#!d
void main()
{    
    int myint = 1234;
    char* mystring = "This number -> %d <- should be 1234\n";
    
    asm
    {
            push    dword ptr myint     ; // pointer to the integer variable declared in D 
            push    dword ptr mystring  ; // pointer into the C-style string declared in D
            call    printf              ; // call the printf function
    }


    /*
        This piece of code is the assembly equivalent of the C/D code
                
            int myint = 1234; 
            printf("This number -> %d <- should be 1234\n", myint);        
    */
}
}}}

== Expected Output ==
{{{
This number -> 1234 <- should be 1234
}}}

== More Information ==

Inspired by a code snippet found at in the [http://home.comcast.net/%7Efbkotler/nasmdoc8.html#section-8.1.2 NASM manual].

For more details regarding asm blocks in D, check out the [http://www.digitalmars.com/d/iasm.html D Specification].

This example was tested on a x86 machine. I don't have any idea whether it'd work on any other platforms.
