The first argument is the target directory -where the source code to be patched is saved. The second argument is the directory where the patch is saved. The third argument is the filename pattern -to match when looking in the patch directory. The third argument can include wildcards to select multiple patch files. -</p> - -<!--#include file="footer.html" --> |
