NAME
genders_getattr - get attributes from a genders file
SYNOPSIS
#include <genders.h>
int genders_getattr(genders_t handle, char *attrs[], char *vals[], int
len, const char *node);
DESCRIPTION
genders_getattr() gets the attributes and values for the node pointed
to by node. If node is NULL, attributes and values are retrieved for
the current node. The attributes are stored in the attribute list
pointed to by attrs and the attribute values are stored in vals. If
attribute values are not desired, vals can be set to NULL. len should
indicate the number of elements that can be stored in both the
attribute list and attribute values list.
To avoid passing in a list that is not large enough to store all the
attributes and attribute values, genders_getmaxattrs(3) should be used
to determine the minimum number of elements attrs and vals should be
able to store. genders_attrlist_create(3) and genders_vallist_cre-
ate(3) could be used to create lists that are guaranteed to be large
enough to store all attributes and attribute values.
RETURN VALUES
On success, the number of attributes stored in attrs is returned. On
error, -1 is returned, and an error code is returned in handle. The
error code can be retrieved via genders_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

or if node=NULL, the machine genders is running on is not listed
in the genders database.
