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_NULLHANDLE
              The  handle  parameter  is  NULL.   The  genders  handle  must  be   created   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_handle_destroy(3).
