setgroups

setgroups(2)							System Calls Manual						      setgroups(2)

NAME

       setgroups - set group access list

SYNOPSIS

DESCRIPTION

       sets  the  group  access  list  of  the	current user process according to the array gidset.  The parameter ngroups indicates the number of
       entries in the array and must be no more than

       Only a user with the privilege can set new groups by adding to the group access list of the current  user  process;  any  user  can  delete
       groups from it.

   Security Restrictions
       Some  or  all of the actions associated with this system call require the 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, returns 0; otherwise it returns -1 and sets to indicate the error.

ERRORS

       fails if any of the following conditions are encountered:

	      The caller     is not a user with the privilege and has attempted to set new groups.

	      The address specified for
			     gidset is outside the process address space.  The reliable detection of this error is implementation dependent.

	      ngroups	     is greater than or not positive.

	      An entry in    gidset is not a valid group ID.
