Summary:
When using the dialog version of the Restart command, you can restart
your program with command-line arguments; however, under CodeView
Protect (CVP) versions 2.2 and 2.3, argc does not get properly set.
Microsoft has confirmed this to be a problem with CodeView versions
2.2 and 2.3. This problem was corrected in CodeView version 3.0.
More Information:
The Dialog Restart command is often used to restart a program with
command-line arguments. For example, you could use the following:
L arg1 arg2 arg3
This example restarts the current executable file, retaining any
breakpoints, watchpoints, and tracepoints, with arg1, arg2, and arg3
loaded into argv[1], argv[2], and argv[3], respectively. Argv[0] is
always set to the name of the current executable file. Argc, at this
point, should be set to four. The problem presents itself here; argc
either remains unchanged from the value it was initially set to when
CodeView 2.2 or 2.3 was started, or is decremented by one. If, for
example, CodeView is started with two command-line arguments (argc
would then be set to three) and then executed, the previous example
argc (which should then set argc to four) would remain unchanged. When
using the Dialog Restart command and specifying fewer arguments than
were specified at start up, argc sometimes is decremented by one.
