Description

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.
