Capturing binary output from Process.StandardOutput

Using StandardOutput.BaseStream is the correct approach, but you must not use any other property or method of cmdProcess.StandardOutput. For example, accessing cmdProcess.StandardOutput.EndOfStream will cause the StreamReader for StandardOutput to read part of the stream, removing the data you want to access. Instead, simply read and parse the data from br (assuming you know how to … Read more

How can I create a binary file in Perl?

The Perl pack function will return “binary” data according to a template. open(my $out, ‘>:raw’, ‘sample.bin’) or die “Unable to open: $!”; print $out pack(‘s<‘, 255); close($out); In the above example, the ‘s’ tells it to output a short (16 bits), and the ‘<‘ forces it to little-endian mode. In addition, ‘:raw’ in the call … Read more

Why unsigned int 0xFFFFFFFF is equal to int -1?

C and C++ can run on many different architectures, and machine types. Consequently, they can have different representations of numbers: Two’s complement, and Ones’ complement being the most common. In general you should not rely on a particular representation in your program. For unsigned integer types (size_t being one of those), the C standard (and … Read more
