uint32_t _TIFFClampDoubleToUInt32(double val)

uint32_t _TIFFMultiply32(TIFF *tif, uint32_t first, uint32_t second, const char *where)

uint64_t _TIFFMultiply64(TIFF *tif, uint64_t first, uint64_t second, const char *where)

_TIFFClampDoubleToUInt32() clamps double values into the range of uint32_t (i.e. 0 .. 0xFFFFFFFF)

_TIFFMultiply32() and _TIFFMultiply64() checks for an integer overflow of the multiplication result and return the multiplication result or 0 if an overflow would happen. The string where is printed in the error message in case an overflow happens and can be used to indicate where the function was called.
