Hi all,
I 've below block of code with in a cpp file.

Select all

static const char* U_CALLCONV
ucnv_io_nextStandardAliases(UEnumeration *enumerator,
                            int32_t* resultLength,
                            UErrorCode * /*pErrorCode*/)
{
    UAliasContext *myContext = (UAliasContext *)(enumerator->context);
    uint32_t listOffset = myContext->listOffset;

    if (listOffset) {
        uint32_t listCount = gMainTable.taggedAliasLists[listOffset];
        const uint16_t *currList = gMainTable.taggedAliasLists + listOffset + 1;

        if (myContext->listIdx < listCount) {
            const char *myStr = GET_STRING(currList[myContext->listIdx++]);
            if (resultLength) {
                *resultLength = (int32_t)uprv_strlen(myStr);
            }
            return myStr;
        }
    }
    /* Either we accessed a zero length list, or we enumerated too far. */
    if (resultLength) {
        *resultLength = 0;
    }
    return NULL;
}

Where UEnumeration is declared as

struct UEnumeration {
    void *baseContext;
    void *context;

    UEnumClose *close;
    UEnumCount *count;
    UEnumUNext *uNext;
    UEnumNext  *next;   <==
    UEnumReset *reset;
};

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
UEnumNext is declared as

typedef const char* U_CALLCONV
UEnumNext(UEnumeration* en,
           int32_t* resultLength,
           UErrorCode* status);

While compiling i am getting below errors on z/OS (USS) getting below error.

"/usr/local/ICU1510/src/source/common/ucnv_io.cpp", line 824.5: CCN5257 (S) An object or reference of type "UEnumNext *" cannot be initialized with an expression of type "char *(UEnumeration *, int32_t *, UErrorCode *)".

I could see there is no mismatch in the prototypes.
Not sure why it is not getting initialized. Same code works fine on Linux/Windows OS.

Any solution/workaround for this on z/OS?

For a start, which is line 824.5???

Hi,

The Line 824 is
