Hi all,

I have found what the error is because of the below code. The problem is
that eventhough the "len" is "0" during the return, the "length" is assigned
with a value "-4" instead of "0" . Can any one please let me know why this
happening? T(this happening only with AIX). I tried changing "size_t len" to
"TDS_INT len" but it didn't worked.



static TDS_INT

binary_to_result(const void *data, size_t len, CONV_RESULT * cr)

{

     cr->ib = (TDS_CHAR *) malloc(len);

     test_alloc(cr->ib);

     memcpy(cr->ib, data, len);

     return len;

}



static TDS_INT

tds_convert_char(int srctype, const TDS_CHAR * src, TDS_UINT srclen,
intdesttype, CONV_RESULT * cr)

{

     :

case CASE_ALL_BINARY:

           return binary_to_result(src, srclen, cr);

           break;

*            :*

TDS_INT

tds_convert(TDSCONTEXT * tds_ctx, int srctype, const TDS_CHAR * src,
TDS_UINT srclen, int desttype, CONV_RESULT * cr)

{

     :

     case SYBLONGBINARY:

     case CASE_ALL_BINARY:

           length = tds_convert_binary(srctype, (const TDS_UCHAR *) src,
srclen, desttype, cr);

           break;

     :

     return length;

}

*Thanks,*
