|
|
||||||
.Nm \&procctl
|
|
||||||
clears the
|
|
||||||
.Xr procfs 5
|
|
||||||
event mask used by
|
|
||||||
.Xr truss 1 .
|
|
||||||
This can be used in the event that a process is left stranded, since
|
|
||||||
the
|
|
||||||
.Xr procfs 5
|
|
||||||
events result in a non-killable process.
|
|
||||||
The options are a list of process ID's;
|
|
||||||
.Nm \&procctl
|
|
||||||
goes through the list and clears the event masks for each specified process.

.Sh HISTORY
|
|
||||||
The
|
|
||||||
.Nm procctl
|
|
||||||
command was written by Sean Eric Fagan for FreeBSD.

* procctl -- clear the event mask, and continue, any specified processes.
|
|
||||||
* This is largely an example of how to use the procfs interface; however,
|
|
||||||
* for now, it is also sometimes necessary, as a stopped process will not
|
|
||||||
* otherwise continue. (This will be fixed in a later version of the
|
|
||||||
* procfs code, almost certainly; however, this program will still be useful
|
|
||||||
* for some annoying circumstances.)
