 NAME
      setuid(), setgid() - set user and group IDs

 SYNOPSIS
      #include <unistd.h>

      int setuid(uid_t uid);

      int setgid(gid_t gid);

 DESCRIPTION
      setuid() sets the real-user-ID (ruid), effective-user-ID (euid),
      and/or saved-user-ID (suid) of the calling process.  If the Security
      Containment product is installed, these interfaces treat a process
      observing CHSUBJIDENT as a privileged process.  Otherwise, only
      processes with an euid of zero are treated as privileged processes.
      See privileges(5) for more information on Security Containment and
      fine-grained privileges.

      The following conditions govern setuid's behavior:

	   +  If the process is privileged, setuid() sets the ruid, euid,
	      and suid to uid.

	   +  If the process is not privileged and the argument uid is equal
	      to the ruid or the suid, setuid() sets the euid to uid; the
	      ruid and suid remain unchanged.  (If a set-user-ID program is
	      not running as superuser, it can change its euid to match its
	      ruid and reset itself to the previous euid value.)

	   +  If the process is not privileged, the argument uid is equal to
	      the euid, and the calling process has the PRIV_SETRUGID
	      privilege, setuid() sets the ruid to uid; the euid and suid
	      remain unchanged.

      setgid() sets the real-group-ID (rgid), effective-group-ID (egid),
      and/or saved-group-ID (sgid) of the calling process.  The following
      conditions govern setgid()'s behavior:

	   +  If the process is privileged, setgid() sets the rgid and egid
	      to gid.

	   +  If the process is not privileged and the argument gid is equal
	      to the rgid or the sgid, setgid() sets the egid to gid; the
	      rgid and sgid remain unchanged.

	   +  If the process is not privileged, the argument gid is equal to
	      the egid, and the calling process has the PRIV_SETRUGID
	      privilege, setgid() sets the rgid to gid; the egid and sgid
	      remain unchanged.

    Security Restrictions
      Some or all of the actions associated with this system call require
      the CHSUBJIDENT privilege.  Processes owned by the superuser have this
      privilege.  Processes owned by other users may have this privilege,
      depending on system configuration.

      See privileges(5) for more information about privileged access on
      systems that support fine-grained privileges.

 RETURN VALUE
      Upon successful completion, setuid() and setgid() return 0; otherwise,
      they return -1 and set errno to indicate the error.

 ERRORS
      setuid() and setgid() fail and return -1 if any of the following
      conditions are encountered:

	   [EPERM]	  None of the conditions above are met.

	   [EINVAL]	  uid (gid) is not a valid user (group) ID.

 WARNINGS
      It is recommended that the PRIV_SETRUGID capability be avoided, as it
      is provided for backward compatibility.  This feature may be modified
      or dropped from future HP-UX releases.  When changing the real user ID
      and real group ID, use of setresuid() and setresgid() (see
      setresuid(2)) is recommended instead.

 AUTHOR
      setuid() was developed by AT&T, the University of California,
      Berkeley, and HP.

      setgid() was developed by AT&T.

 NAME
      setreuid - set real and effective user IDs

 SYNOPSIS
      #include <unistd.h>

      int setreuid(uid_t ruid, uid_t euid);

 DESCRIPTION
      The setreuid() function sets the real and effective user IDs of the
      current process to the values specified by the ruid and euid
      arguments. If ruid or euid is -1, the corresponding effective or real
      user ID of the current process is left unchanged.

      A process with appropriate privileges can set either ID to any value.
      An unprivileged process can only set the effective user ID if the euid
      argument is equal to either the real, effective, or saved user ID of
      the process.

      It is unspecified whether a process without appropriate privileges is
      permitted to change the real user ID to match the current real,
      effective or saved user ID of the process.

 RETURN VALUE
      Upon successful completion, 0 is returned. Otherwise, -1 is returned
      and errno is set to indicate the error.

 ERRORS
      The setreuid() function will fail if:

	   [EINVAL]		    The value of the ruid or euid argument
				    is invalid or out-of-range.

	   [EPERM]		    The current process does not have
				    appropriate privileges, and either an
				    attempt was made to change the effective
				    user ID to a value other than the real
				    user ID or the saved set-user-ID or an
				    attempt was made to change the real user
				    ID to a value not permitted by the
				    implementation.

 NAME
      setresuid, setresgid - set real, effective, and saved user and group
      IDs

 SYNOPSIS
      #include <unistd.h>

      int setresuid(uid_t ruid, uid_t euid, uid_t suid);

      int setresgid(gid_t rgid, gid_t egid, gid_t sgid);

 DESCRIPTION
      setresuid() sets the real, effective and/or saved user ID of the
      calling process.

      If the current real, effective or saved user ID is equal to that of a
      user having appropriate privileges, setresuid() sets the real,
      effective and saved user IDs to ruid, euid, and suid, respectively.
      Otherwise, setresuid() only sets the real, effective, and saved user
      IDs if ruid, euid, and suid each match at least one of the current
      real, effective, or saved user IDs.

      If ruid, euid, or suid is -1, setresuid() leaves the current real,
      effective or saved user ID unchanged.

      setresgid() sets the real, effective and/or saved group ID of the
      calling process.

      If the current real, effective or saved user ID is equal to that of a
      user having appropriate privileges, setresgid() sets the real,
      effective, and saved group ID to rgid, egid, and sgid, respectively.
      Otherwise, setresgid() only sets the real, effective and saved group
      ID if rgid, egid, and sgid each match at least one of the current
      real, effective or saved group ID.

      If rgid, egid, or sgid is -1, setresgid() leaves the current real,
      effective or saved group ID unchanged.

    Security Restrictions
      Some or all of the actions associated with this system call require
      the PRIV_CHSUBJIDENT privilege (CHSUBJIDENT).  Processes owned by the
      superuser will have this privilege.  Processes owned by other users
      may have this privilege, depending on system configuration.  See
      privileges(5) for more information about privileged access on systems
      that support fine-grained privileges.

 RETURN VALUE
      Upon successful completion, setresuid() and setresgid() return 0;
      otherwise, they return -1 and set errno to indicate the error.
