SETGID(2)						     Linux Programmer's Manual							 SETGID(2)

NAME

       setgid - set group identity

SYNOPSIS

       #include <sys/types.h>
       #include <unistd.h>

       int setgid(gid_t gid);

DESCRIPTION

       setgid()  sets the effective group ID of the calling process.  If the caller is the superuser, the real GID and saved set-group-ID are also
       set.

       Under Linux, setgid() is implemented like the POSIX version with the _POSIX_SAVED_IDS feature.  This allows a set-group-ID program that	is
       not  set-user-ID-root to drop all of its group privileges, do some un-privileged work, and then reengage the original effective group ID in
       a secure manner.

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS

       EPERM  The calling process is not privileged (does not have the CAP_SETGID capability), and gid does not match the real group ID  or  saved
	      set-group-ID of the calling process.

CONFORMING TO

       SVr4, POSIX.1-2001.

       This  page is part of release 3.27 of the Linux man-pages project.  A description of the project, and information about reporting bugs, can
