NAME
genders_getnumnodes, genders_getnumattrs, genders_getmaxattrs, gen-
ders_getmaxnodelen, genders_getmaxattrlen, genders_getmaxvallen - gen-

SYNOPSIS
#include <genders.h>
int genders_getnumnodes(genders_t handle);
int genders_getnumattrs(genders_t handle);
int genders_getmaxattrs(genders_t handle);
int genders_getmaxnodelen(genders_t handle);
int genders_getmaxattrlen(genders_t handle);
int genders_getmaxvallen(genders_t handle);
DESCRIPTION
genders_getnumnodes(), genders_getnumattrs(), genders_getmaxattrs(),
genders_getmaxnodelen(), genders_getmaxattrlen(), and genders_getmax-
vallen() 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_get-
maxattrs(), genders_getmaxnodelen(), genders_getmaxattrlen(), and gen-
ders_getmaxvallen() are used so a programmer can dynamically allocate a
proper amount of memory to store genders file information in.
RETURN VALUES
On success, 0 is returned. On error, -1 is returned, and an error code
is returned in handle. The error code can be retrieved via gen-
ders_errnum(3) , and a description of the error code can be retrieved
via genders_strerror(3). Error codes are defined in genders.h.
ERRORS
GENDERS_ERR_NULLHANDLE
The handle parameter is NULL. The genders handle must be cre-
ated with genders_handle_create(3).
GENDERS_ERR_NOTLOADED
genders_load_data(3) has not been called to load genders data.
GENDERS_ERR_MAGIC
handle has an incorrect magic number. handle does not point to
a genders handle or handle has been destroyed by genders_han-
dle_destroy(3).
