Test::HexDifferences Optionen 2/2

Test::HexDifferences Default-Format

"%a : %4C : %d\n"

oder komplett geschrieben

"%a : %4C : %d\n%*x"

Wenn die Daten länger als das Format sind, greift wieder das default Format.

%n  - unsigned 16-bit, big-endian
%L  - unsigned 32-bit, endian depends on machine
%L< - unsigned 32-bit, little-endian
%L> - unsigned 32-bit, big-endian
%V  - unsigned 32-bit, little-endian
%N  - unsigned 32-bit, big-endian

%Q< - unsigned 64-bit, little-endian
%Q> - unsigned 64-bit, big-endian

Test::HexDifferences Adress-Format

%a  - 16 bit address
%4a - 16 bit address
%8a - 32 bit address

Test::HexDifferences ASCII-Format

%d - ASCII anzeigen, was nicht geht als .

Test::HexDifferences Wiederholung
