NAME

     setlcid -- set login context

SYNOPSIS

     #include <sys/lctx.h>

     int
     setlcid(pid_t pid, pid_t lcid);

DESCRIPTION

     The setlcid() system call sets the login context of the specified process pid to the specified lcid.  If the pid is zero, then the call
     applies to the current process.  If the lcid is zero a new login context will be created.	If the lcid is -1 the process will be removed from
     the login context it is currently a member of, if any.

     Creation of a new login context is only valid for the current process.  A process may not create a new login context if it is currently a
     member of one.

     Superuser privilege is required to add or remove a process from a login context.

RETURN VALUES

     The setlcid() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS

     The setlcid() function will fail if:

     [EPERM]		Operation not permitted.

     [ESRCH]		No such process.

     [ENOMEM]		Cannot allocate memory.

     [ENOATTR]		Attribute not found.

SETPGID(2)						      BSD System Calls Manual							SETPGID(2)

NAME

     setpgid, setpgrp -- set process group

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     setpgid(pid_t pid, pid_t pgrp);

     int
     setpgrp(pid_t pid, pid_t pgrp);

DESCRIPTION

     setpgid() sets the process group of the specified process pid to the specified pgrp.  If pid is zero, then the call applies to the current
     process.  If pgrp is zero, then the process id of the process specified by pid is used instead.

     If the invoker is not the super-user, then the affected process must have the same effective user-id as the invoker or be a descendant of the
     invoking process.

RETURN VALUES

     setpgid() returns 0 when the operation was successful.  If the request failed, -1 is returned and the global variable errno indicates the
     reason.

ERRORS

     setpgid() will fail and the process group will not be altered if:

     [EACCES]		The value of the pid argument matches the process ID of a child process of the calling process, and the child process has
			successfully executed one of the exec functions.

     [EINVAL]		The value of the pgrp argument is less than zero.

     [EPERM]		The effective user ID of the requested process is different from that of the caller and the process is not a descendant of
			the calling process.

     [ESRCH]		The value of the pid argument does not match the process ID of the calling process or of a child process of the calling
			process.

SEE ALSO

     getpgrp(2)

STANDARDS

     The setpgid() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').

COMPATIBILITY

     setpgrp() is identical to setpgid(), and is retained for calling convention compatibility with historical versions of BSD.
