Assembly language in C

I was reading an article on assembly language in wikipedia and was a little suprised to read this line.
>>Relatively low-level languages, such as C, often provide special syntax to
>>embed assembly language directly in the source code.
Any ideas how to do that? Is it compiler specific?

inline asm. http://www.ibiblio.org/gferg/ldp/GCC...bly-HOWTO.html

It is compiler specific, but that's a pretty good explanation above. Another common syntax is

Code:

---

asm { ... }

---

(IIRC that's what Borland compilers use)

As stated, it is compiler specific, so each compiler (that supports inline assembler at all) will have it's own variant.

MS Visual Studio uses the

Code:

---

asm { ... }

---

format.

So if im using code blocks on linux, which im pretty sure uses gcc, the format would be asm("")?

Yup, and that would work in windows using gcc too [as long as the assembler itself doesn't rely on unportable constructs - e.g. calling system calls or functions that aren't present on the other architecture]. And if you want to be ANSI compatible use __asm__.
