.Dd May 11, 2016 .Dt PSETZONEID 3PROC .Os .Sh NAME .Nm Psetzoneid .Nd change processes zone id .Sh SYNOPSIS .Lb libproc n libproc.h .Ft int .Fo Psetzoneid .Fa "struct ps_prochandle *P" .Fa "zoneid_t zoneid" .Fc .Sh DESCRIPTION The .Fn Psetzoneid function moves the process handle .Fa P into the zone specified by .Fa zoneid . A process that is in the non-global zone may only move between the global zone and its original zone. A process that is in the global zone may not use this interface to enter a non-global zone. This function will fail if called from a non-global zone. This function only manipulates the processes credentials.

p Care should be taken when moving a process around temporarily, such that if the process that is manipulating .Fa P dies, it does not cause .Fa P to resume running while still in the global zone. It is suggested that the .Sy PR_KLC flag is set with .Xr Psetflags 3PROC which will cause the process to terminate if the process that holds .Fa P unexpectedly terminates. See .Xr proc 4 for more information on the .Sy PR_KLC flag.

p Note, only active processes may change their zone. It is an error to call this function on process handles that correspond to core files, zombie processes, or files. .Sh RETURN VALUES Upon successful completion, the .Fn Psetzoneid function returns .Sy 0 and changes the zone for .Fa P . Otherwise, .Sy -1 is returned and .Sy errno is set. .Sh ERRORS For a full list of possible errors see the .Sy DIAGNOSTICS section in .Xr proc 4 .

p The .Fn Psetzoneid function will fail if: l -tag -width Er t Er EINVAL .Fa zoneid does not correspond to an existing zone or the zone id is not the global zone or the original zone of .Fa P . t Er EPERM The caller does not hold the required privileges for zone configuration. .El .Sh INTERFACE STABILITY .Sy Uncommitted .Sh MT-LEVEL See .Sy LOCKING in .Xr libproc 3LIB . .Sh SEE ALSO .Xr libproc 3LIB , .Xr proc 4 , .Xr privileges 5 , .Xr zones 5
