SETGROUPS(2)              FreeBSD System Calls Manual             SETGROUPS(2)

NAME
     setgroups - set group access list

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/param.h>
     #include <unistd.h>

     int
     setgroups(int ngroups, const gid_t *gidset);

DESCRIPTION
     The setgroups() system call sets the group access list of the current
     user process according to the array gidset.  The ngroups argument
     indicates the number of entries in the array and must be no more than
     NGROUPS, as defined in <sys/param.h>.

     Only the super-user may set new groups.

RETURN VALUES
     The setgroups() 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 setgroups() system call will fail if:

     [EPERM]            The caller is not the super-user.

     [EINVAL]           The number specified in the ngroups argument is larger
                        than the NGROUPS limit.

     [EFAULT]           The address specified for gidset is outside the
                        process address space.

SEE ALSO
     getgroups(2), initgroups(3)

HISTORY
     The setgroups() system call appeared in 4.2BSD.
