asm help

[flyker]

Can anybody help me write the function for Linux :

__declspec(naked) BOOL WINAPI 
_InitCommonControlsEx(INITCOMMONCONTROLSEX* lpInitCtrls)
{
   if(!dwLPA_InitCommonControlsEx)
   {
       __asm mov eax, 0
       __asm ret 4
   }
   else
   {
       __asm jmp dwLPA_InitCommonControlsEx
   }
}

May be :
__declspec(naked) BOOL WINAPI 
_InitCommonControlsEx(WINGS_INITCOMMONCONTROLSEX* lpInitCtrls)
{
   if(!dwLPA_InitCommonControlsEx)
   {
   __asm__ __volatile__("movl 0, %eax");
   __asm__ __volatile__("ret");
   }
   else
   {
   __asm__ __volatile__("jmp %0" : : "q"(dwLPA_InitCommonControlsEx));
   }
}
