inline function in visual c++ 6.0

I have some static bool inline function in the project (it's not my code):

static bool inline
is_safe_raw(CHAR_DATA *ch, CHAR_DATA *victim)
{
    /*
     * ghosts are safe
     * this check must be done first to avoid
     * suicyco who recite 'leather-bound book' (#5743)
     * without any target specified
     * extracted NPCs are safe too
     */
    if (!IS_NPC(victim)) {
        int clan;

        /* ghost cannot attack anyone */
        if (ch != victim
        &&  !IS_NPC(ch)
        &&  IS_SET(ch->plr_flags, PLR_GHOST))
            return TRUE;

        /* clan defenders can attack anyone in their clan */
        if (victim->in_room
        &&  (clan = victim->in_room->area->clan)
        &&  victim->clan != clan
        &&  ch->clan == clan)
            return FALSE;

        /* otherwise ghosts are safe */
        if (IS_SET(victim->plr_flags, PLR_GHOST开发者_如何学JAVA))
            return TRUE;
    }
    else if (victim->extracted)
        return TRUE;

    if (victim->fighting == ch
    ||  ch == victim
    ||  IS_IMMORTAL(ch))
        return FALSE;

    /* handle ROOM_PEACE flags */
    if ((victim->in_room && IS_SET(victim->in_room->room_flags, ROOM_PEACE))
    ||  (ch->in_room && IS_SET(ch->in_room->room_flags, ROOM_PEACE)))
        return TRUE;

    /* link dead players whose adrenalin is not gushing are safe */
    if (!IS_NPC(victim) && !IS_PUMPED(victim) && victim->desc == NULL)
        return TRUE;

    return !in_PK(ch, victim);
}

I'm trying to compile (make) it using Visual C++ 6.0 NMake (the project is '98 year) and it throws this error:

If I get out "inline" modifier - it compiles well. But I can't understand why. Could somebody explain it to me?

Your source file has .c extension, which means that by default it will be compiled as C language source file. The compiler you are using is implementing the C89/90 version of C language, which does not have such thing as inline. Hence the error.

If this is supposed to be C++ code (and your question is tagged [C++]), you have to either give your file .cpp extension or use a compiler switch that would force the compiler to treat the file as C++ code.

If this is supposed to be C code, then with this compiler your are restricted to C89/90, which has no inline at all. The compiler might support some alternative keyword for function inlining as an extension. Could be _inline or __inline or something like that.

First of all, inline is delacred first, and second inline is only declared in header file. Hope that helps!

Perhaps someone has done a #define of inline to something unhelpful? You could try examining the preprocessor output (/E, I think) to see exactly what the compiler is seeing.

Have you tried one of the other variants, such as "__inline"?
