:arrest

Arguments: process &rest processes

Arrests for debugging all processes given as arguments. The processes are arrested by adding :debugging to the list of arrest reasons for each process. Note that the listener process cannot be arrested.

The process and processes argument can specify as many processes as desired. Each argument can be:

• A string, which is processed as described below.
• A symbol, which is evaluated to produce a process object, a string, an integer, or a symbol. If the value is a symbol, its print name is used as if that were the string provided.
• A list, which is evaluated to produce a process object, a string, an integer, or a symbol. If the value is a symbol, its print name is used as if that were the string provided.
• An integer, which designated the process whose process-sequence value is that integer.

Strings are compared with process names. All processes whose names exactly match the string are considered matches. If no process name exactly matches, then all processes whose names contain the string as a substring are considered matches. (For example, if there are processes with names "Listener 1" and "Initial Lisp Listener", both match the string "ener".) For this command, multiple matches of parts of names with the string are considered ambiguous and the command fails with a diagnostic.

Strings which match no process cause the command to fail with a diagnostic.

The minimal abbreviation of :arrest is :arr.
