It allows to put data from stdin to clipboard and print clipboard content to the stdout. It automatically detects that STDIN (STDOUT) is pipe or file and chooses appropriate mode. Each mode can be forced to allow program to work with character devices (console/COMx/etc). Because modes are not exclusive, it is possible to put this utility in the mid of pipe and get pipe content mirrored in clipboard. Examples: 1. Program output to clipboard: [C:\]dir | clip 2. Clipboard to program output: [C:\]clip | more 3. Pipe between programs: [C:\]dir | clip | more 4. Force stdin: [C:\]clip -i type> Some test string ^Z 5. Force stdout: [C:\]clip -o Some test string Hope it will be useful not only for me :-) Comments and suggestions are welcome. Compile with VAC++ 3.08: icc -O+ -Oc+ -Ss+ -Gs+ -Gl+ -G5 -Q+ -Gm+ -B"/ST:32768 /NOE /E:2" clip.cpp Compile with WATCOM C++ 10.6: wcl386 -oneatx clip.cpp Simple command line for both compilers works too: icc clip.cpp wcl386 clip.cpp ----------- cut ----------- /* ** Module :CLIP.CPP ** Abstract :Clipboard command line utility ** ** Public domain by Sergey I.
