The fields of a process are:
- A string, the name of the process.
- A list containing the command arguments that were used to start this
- A function used to accept output from the process instead of a buffer,
- A function called whenever the process receives a signal, or
- The associated buffer of the process.
- An integer, the Unix process ID.
- A flag, non-
nil if this is really a child process.
nil for a network connection.
- A marker indicating the position of the end of the last output from this
process inserted into the buffer. This is often but not always the end
of the buffer.
- If this is non-
nil, killing XEmacs while this process is still
running does not ask for confirmation about killing the process.
- These two fields record 16 bits each of the process status returned by
wait system call.
- The process status, as
process-status should return it.
- If these two fields are not equal, a change in the status of the process
needs to be reported, either by running the sentinel or by inserting a
message in the process buffer.
nil if communication with the subprocess uses a PTY;
nil if it uses a pipe.
- The file descriptor for input from the process.
- The file descriptor for output to the process.
- The file descriptor for the terminal that the subprocess is using. (On
some systems, there is no need to record this, so the value is
- The name of the terminal that the subprocess is using,
nil if it is using pipes.
39.0.1 Ben's separate stderr notes (probably obsolete)
This node contains some notes that Ben kept on his separate subprocess
workspace. These notes probably describe changes and features that have
already been included in XEmacs 21.5; somebody should check and/or ask
this is an old workspace, very close to being done, containing
subprocess stderr output can be read separately; needed to fully
implement call-process with asynch. subprocesses.
huge improvements to the internal error-trapping routines (i.e. the
routines that call Lisp code and trap errors); Lisp code can now be
called from within redisplay.
cleanup and simplification of C-g handling; some things work now
that never used to.
see the ChangeLogs in the workspace.
