Notes

RunCmd() is called when the client needs to call an external program, such as a merge or diff utility. RunCmd() stores any resulting errors in the specified Error object.

Example

If you select "d" for "Diff" during an interactive resolve, and both P4DIFF and P4PAGER are set in your environment, RunCmd() is called with the following arguments:

Argument	Value
command	P4DIFF
arg1	local file name
arg2	temp file name (depot file)
arg3	null
arg4	null
pager	P4PAGER

The P4DIFF program is called with the two file names as arguments, and the output is piped through the P4PAGER program.

See the examples for Diff() and Merge() for code illustrating the use of RunCmd().
