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.  genders_nodelist_create(3) could be used to create a list that is guaranteed 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_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.
