Hi there, I have this function in C: 
TM_PageTranslation* findPageByEffective(u32 lpid, u32 pid, u64 EA);

[download]
These are the types of each parameter: TM_PageTranslation - C struct u32 - unsigned int u64 - unsigned long long int This is my typemap: 
TYPEMAP
T_PageTranslation     T_PTROBJ
u64                   T_U_LONG_LONG
u64 *                 T_OPAQUEPTR
u32 *                 T_OPAQUEPTR
u32                   T_U_INT
##################################################
INPUT
T_U_LONG_LONG
    $var = (unsigned long long int)SvUV($arg)
##################################################
OUTPUT
T_U_LONG_LONG
    sv_setuv($arg, (UV)$var);

(T_U_INT is defined in the default typemap) this is my XS code: 
typedef struct TM_PageTranslation * T_PageTranslation;
...
T_PageTranslation
findPageByEffective(lpid, pid, EA)
        u32 lpid
        u32 pid
        u64 EA

When I run the make command I get the following warning: "trans.c:470: warning: assignment from incompatible pointer type" line 470 int rans.C is this: 
XS(XS_trans_findPageByEffective); /* prototype to pass -Wmissing-proto
+types */
XS(XS_trans_findPageByEffective)
{
#ifdef dVAR
    dVAR; dXSARGS;
#else
    dXSARGS;
#endif
    if (items != 3)
       croak_xs_usage(cv,  "lpid, pid, EA");
    {
    u32    lpid = (unsigned int)SvUV(ST(0));
    u32    pid = (unsigned int)SvUV(ST(1));
    u64    EA = (unsigned long long int)SvUV(ST(2));
    T_PageTranslation    RETVAL;

    RETVAL = findPageByEffective(lpid, pid, EA); <--- This is line 470
    ST(0) = sv_newmortal();
    sv_setref_pv(ST(0), "T_PageTranslation", (void*)RETVAL);
    }
    XSRETURN(1);
}

How do I fixed this?
