.SH SYNOPSIS

|
\fBpid \fR?\fIfileId\fR?
|
|
.BE

|
|
|
.SH DESCRIPTION
|
|
.PP
|
|
If the \fIfileId\fR argument is given then it should normally
|
|
refer to a process pipeline created with the \fBopen\fR command.
|
|
In this case the \fBpid\fR command will return a list whose elements
|
|
are the process identifiers of all the processes in the pipeline,
|
|
in order.
|
|
The list will be empty if \fIfileId\fR refers to an open file
|
|
that isn't a process pipeline.
|
|
If no \fIfileId\fR argument is given then \fBpid\fR returns the process
|
|
identifier of the current process.
|
|
All process identifiers are returned as decimal strings.
|
|
|
|
.SH KEYWORDS

file, pipeline, process identifier
