NAME¶
zvbi-chains - VBI proxy wrapper
SYNOPSIS¶
zvbi-chains [ options ]
DESCRIPTION¶
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 environment
variables.
OPTIONS¶
- -dev path
- Path of a VBI device from which to read data.
- -debug level
- Enables debug output: 0 = off (default); 1 = warnings, 2 = all
messages.
- -help
- Print a short description of all command line options.
