* Name: binfmt_copyargv

* Description:
|

* address environment and, hence, by inaccessible when we switch to the

|
* address environment of the new process address environment. So we
|
|
* do not have any real option other than to copy the callers argv[] list.

*
|
|
* Input Parameters:

|
* bin - Load structure
|

* argv - Argument list
