.Fn cap_sandboxed "void"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
.Fn cap_sandboxed
|
||
|
|
returns
|
||
|
|
.Va true
|
||
|
|
if the process is in a capability mode sandbox or
|
||
|
|
.Va false
|
||
|
|
if it is not.
|
||
|
|
This function is a more handy alternative to the
|
||
|
|
.Xr cap_getmode 2
|
||
|
|
system call as it always succeeds, so there is no need for error checking.
|
||
|
|
If the support for capability mode is not compiled into the kernel,
|
||
|
|
.Fn cap_sandboxed
|
||
|
|
will always return
|
||
|
|
.Va false .
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
Function
|
||
|
|

|
||
|
|
is always successful and will return either
|
||
|
|
.Va true
|
||
|
|
or
