zvbi-chains - VBI proxy wrapper
zvbi-chains [ options ]
zvbi-chains is a small wrapper which executes the VBI application given
on the command line while overloading several C library calls (such as
open(2) and read(2)) so that the application can be forced to access
VBI devices via the VBI proxy instead of device files directly.
LD_PRELOAD is used to intercept C library calls and call functions in
the libzvbi-chain shared library instead. Parameters given on the
command line (e.g. device path) are passed to the library by means of
Path of a VBI device from which to read data.
Enables debug output: 0 = off (default); 1 = warnings, 2 = all
-help Print a short description of all command line options.
