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

723 BUFFER is the buffer or (buffer-name) to associate with the process.

724 Process output goes at end of that buffer, unless you specify

|

725 an output stream or filter function to handle the output.
|

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

727 with any buffer.

728 BUFFER can also have the form (REAL-BUFFER STDERR-BUFFER); in that case,

|
|
|
731 STDERR-BUFFER may be nil (discard standard error output, unless a stderr
|
|
|
732 filter is set). Note that if you do not use this form at process creation,
|
|
|
733 stdout and stderr will be mixed in the output buffer, and this cannot be
|
|
|
734 changed, even by setting a stderr filter.
|
|
428
|
735 Third arg is program file name. It is searched for as in the shell.
|
|
|
736 Remaining arguments are strings to give program as arguments.
|
|
853
|
737
|
|

740 overriding coding systems to be *bound* by Lisp code, not set), or

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

982 BUFFER is the buffer (or buffer-name) to associate with the process.
|
|
|
983 Process output goes at end of that buffer, unless you specify
|
|
|
984 an output stream or filter function to handle the output.
|
|
|
985 BUFFER may also be nil, meaning that this process is not associated
|
|
|
986 with any buffer.
|
|
|
987 Third, fourth and fifth args are the multicast destination group, port and ttl.
|
|
|
988 dest must be an internet address between 224.0.0.0 and 239.255.255.255
|
|
|
989 port is a communication port like in traditional unicast
|
|
|
990 ttl is the time-to-live (15 for site, 63 for region and 127 for world)
