642 NAME is name for process. It is modified if necessary to make it unique.

643 BUFFER is the buffer or (buffer-name) to associate with the process.
|
|
|
644 Process output goes at end of that buffer, unless you specify

|

645 an output stream or filter function to handle the output.

646 BUFFER may be also nil, meaning that this process is not associated

647 with any buffer.

651 STDERR-BUFFER may be nil (discard standard error output, unless a stderr
|
|
|
652 filter is set). Note that if you do not use this form at process creation,
|
|
|
653 stdout and stderr will be mixed in the output buffer, and this cannot be
|
|
|
654 changed, even by setting a stderr filter.
|
|
428
|
655 Third arg is program file name. It is searched for as in the shell.

|
656 Remaining arguments are strings to give program as arguments.

2613 it sends a non-ending stream of zero bytes. It's used most often along

2614 with memory-mapping. We don't provide a Lisp variable for this because

2615 the operations needing this are lower level than what ELisp programs

2616 typically do, and in any case no equivalent exists under native MS Windows.
