SYNOPSIS
wpatch source-file destination-file wdelta-file
DESCRIPTION
WPatch applies the wdelta-file onto the source-file and creates the
destination-file. The source-file is verified by an crc16-sum which is
contained in the wdelta-file to be equal to the original file the wdelta-
file has been created for. The resulting destination-file is also verified
by an crc16-sum. On success WPatch writes the destination-file.
OPTIONS
source-file
source file which should be converted into the destination-file
destination-file
file which should be created based on the source-file
wdelta-file
differences file created by WDelta
RESULTS
On success WPatch writes the destination-file and returns with a return
code equal zero. Any other return code indicates an failure.
The following list describes all possible return codes:
0 .. success
1 .. wdelta-file is not a wdelta file
2 .. chksum error in wdelta file
3 .. wrong source-file
4 .. error in applying wdelta file
