NAME
genders_getnodes - get nodes from the genders file
SYNOPSIS
#include <genders.h>
int genders_getnodes(genders_t handle, char *nodes[], int len, const
char *attr, const char *val);
DESCRIPTION
genders_getnodes() gets the names of nodes in the genders file that
have the attribute specified by attr and the value specified by val.
The nodes are stored in the list pointed to by nodes. len indicates
the number of nodes that can be stored in the list. If attr is NULL,
genders_getnodes() returns all the nodes listed in the genders file.
If val is NULL, attribute values are ignored.
To avoid passing in a list that is not large enough to store all the
nodes, genders_getnumnodes(3) should be used to determine the minimum
number of elements nodes should be able to store. gen-
ders_nodelist_create(3) could be used to create a list that is guaran-
teed to be large enough to store all of the nodes.
RETURN VALUES
On success, the number of nodes stored in nodes 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
genders_load_data(3) has not been called to load genders data.
GENDERS_ERR_OVERFLOW
The list pointed to by nodes is not large enough to store all
the nodes.
GENDERS_ERR_PARAMETERS
An incorrect parameter has been passed in.
GENDERS_ERR_NULLPTR
A null pointer has been found in the list passed in.
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).
