HOW TO ACCESS PROCESS INFORMATION???

[Tahir N. Khan]

    I've been looking into some very simple process migration
	techniques. Since I am not a unix expert I was wondering if
	anyone out there has any information on how to access
	the state of a process including registers and execution state,
	virtual memory, and file access.

	Any leads to the required steps or what system calls should be 
	used,if any, will be greatly appreciated.

	Please reply either to my email address or post to the
	newsgroup.

    Thanks in advance,
