GETLCID(2)						      BSD System Calls Manual							GETLCID(2)

NAME
     getlcid -- get login context

SYNOPSIS
     #include <sys/lctx.h>

     pid_t
     getlcid(pid_t pid);

DESCRIPTION
     The login context of the process identified by pid is returned by getlcid().  If pid is zero, getlcid() returns the login context of the cur-
     rent process.

     Login contexts are used for tracking processes that originated from a users login session.  A login context is inherited via fork() or by
     explicit creation using the setlcid() call.

RETURN VALUES
     If successful, getlcid() returns a non-negative integer, the Login Context ID; otherwise the value -1 is returned and the global variable
     errno is set to indicate the error.

ERRORS
     The getlcid() function will fail if:

     [EPERM]		Operation not permitted.

     [ESRCH]		No such process.

     [ENOATTR]		Attribute not found.
