genders_getnumnodes(), genders_getnumattrs(),
genders_getmaxattrs(), genders_getmaxnodelen(),
genders_getmaxattrlen(), and genders_getmaxvallen() get
statistics about the genders file associated with handle.
genders_getnumnodes() returns the number of nodes stored in the
genders file.
genders_getnumattrs() returns the number of attributes listed in
the genders file.
genders_getmaxattrs() returns the maximum number of attributes
listed with a node in the genders file.
genders_getmaxnodelen() returns the maximum length of any node
listed in the genders file.
genders_getmaxattrlen() returns the maximum length of any
attribute listed in the genders file.
genders_getmaxvallen() returns the maximum length of any
attribute value listed in the genders file.
In general, genders_getnumnodes(), genders_getnumattrs(),
genders_getmaxattrs(), genders_getmaxnodelen(),
genders_getmaxattrlen(), and genders_getmaxvallen() are
used so a programmer can dynamically allocate a proper amount of
memory to store genders file information in.
