    The function does not calculate groups, it sets groups access list of the current process in accordance to user information in /etc/groups.

    Quote from Unix manual page for initgroups:

    NAME
    initgroups - initialize the supplementary group access list
    ...
    DESCRIPTION
    The initgroups() function initializes the group access list by reading the
    group database /etc/group and using all groups of which user is a member.
    The additional group group is also added to the list.
