class Process::Status
Overview
The status of a terminated process. Returned by Process#wait
.
Defined in:
process/status.crInstance Method Summary
-
#==(other : self)
Returns
true
if this reference is the same as other. -
#exit_code : Int32
If
#normal_exit?
istrue
, returns the exit code of the process. -
#exit_reason : ExitReason
Returns a platform-independent reason why the process terminated.
-
#exit_signal : Signal
If
#signal_exit?
istrue
, returns the Signal the process received and didn't handle. -
#exit_status : Int32
Platform-specific exit status code, which usually contains either the exit code or a termination signal.
- #hash(hasher)
-
#inspect(io : IO) : Nil
Prints a textual representation of the process status to io.
-
#normal_exit? : Bool
Returns
true
if the process terminated normally. -
#signal_exit? : Bool
Returns
true
if the process was terminated by a signal. -
#success? : Bool
Returns
true
if the process exited normally with an exit code of0
. -
#to_s(io : IO) : Nil
Prints a textual representation of the process status to io.
-
#to_s : String
Returns a textual representation of the process status.

Instance Method Detail
Returns true
if this reference is the same as other. Invokes same?
.
If #normal_exit?
is true
, returns the exit code of the process.
If #signal_exit?
is true
, returns the Signal the process
received and didn't handle. Will raise if #signal_exit?
is false
.
Available only on Unix-like operating systems.
NOTE #exit_reason
is preferred over this method as a portable alternative
which also works on Windows.
Platform-specific exit status code, which usually contains either the exit code or a termination signal.
The other Process::Status
methods extract the values from #exit_status
.
Prints a textual representation of the process status to io.
The result is equivalent to #to_s
, but prefixed by the type name and
delimited by square brackets: Process::Status[0]
, Process::Status[1]
,
Process::Status[Signal::HUP]
.
Returns true
if the process exited normally with an exit code of 0
.
Prints a textual representation of the process status to io.
A normal exit status prints the numerical value (0
, 1
etc).
A signal exit status prints the name of the Signal
member (HUP
, INT
, etc.).
Returns a textual representation of the process status.
A normal exit status prints the numerical value (0
, 1
etc).
A signal exit status prints the name of the Signal
member (HUP
, INT
, etc.).
