rtime.doc
This program measures the execution time of a program unde DOS.
The usage is:
"rtime program_to_measure program_options program_arguments"
In other words, your normal command line syntax, preceeded by the
invocation of rtime. Rtime does not eat any of the command line parameters
intended for the application.
Unfortunately, DOS being what it is, this clean and simple usage of rtime
fails when you try to time a batch file. In order to time a batch file
you must spawn a copy of the command line interpreter and pass the batch
file to it. Thus:
"rtime command /c batchfile args"
To make it somewhat easier to use I have added an option flag "-b", which
will cause rtime to invoke the shell itself. Thus:
"rtime -b batchfile args"
This causes rtime to spawn command.com as the child and to pass to command.com
a "/c" as the first parameter, "batchfile" as the second parameter, and "args"
as the subsequent parameters.
Note that rtime options (currently only '-b' exists) must be given as the
first argument on the command line, BEFORE the child name. All other args
are passed on to the child unexamined.
Feel free to use this program as you wish FOR NON-COMMERCIAL purposes.
