Makes an unified diff containing differences between old_file
and
new_file
and stores it in dest
file. The
resulting file is human-readable. An optional context
parameter
specifies how many lines of context should be added around each change (with default value of 3).
Setting minimal
parameter to true will result in outputting the shortest
patch file possible (can take a long time).
Parameters
old_file
Path to the first file. This file acts as "old" file.
new_file
Path to the second file. This file acts as "new" file.
dest
Path of the resulting patch file.
context
Indicates how many lines of context you want to include in diff
result. Default is 3.
minimal
Set this parameter to TRUE if you want to minimalize size of the result
(can take a long time).
Return Values
Returns TRUE on success or FALSE on failure.
