_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.

NAME
_TIFFauxiliary - auxiliary functions
SYNOPSIS
#include <tiffio.h>
uint32_t _TIFFClampDoubleToUInt32(double val)
uint32_t _TIFFMultiply32(TIFF *tif, uint32_t first, uint32_t second,

DESCRIPTION
_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.
