genders 1.10-1 (Default branch)
Genders is a static cluster configuration database used for cluster configuration management. It is used by a variety of tools and scripts for management of large clusters. The genders database is accessed by every node in a cluster, either through a networked file system or by replicating the database on every node of the cluster. The database describes the layout and configuration of the cluster so that tools and scripts can sense the variations of cluster nodes. By abstracting this information into a plain text file, it becomes possible to change the configuration of a cluster by modifying only one file. License: GNU General Public License (GPL) Changes:

genders_load_data

GENDERS_LOAD_DATA(3)						    LIBGENDERS						      GENDERS_LOAD_DATA(3)

NAME

       genders_load_data -  read and parse a genders file

SYNOPSIS

       #include <genders.h>

       int genders_load_data(genders_t handle, const char *filename);

DESCRIPTION

       genders_load_data()  read and parses the genders file indicated by filename.  If filename is NULL, genders_load_data() will attempt to read
       and parse the default genders file defined by DEFAULT_GENDERS_FILE. handle is a genders handle created by genders_handle_create(3).

       After genders_load_data() is called, information about the genders file is stored in the genders handle passed  in.   This  information	is
       used  by  other	genders C API functions.  All future use of handle with other genders C API functions will be directly associated with the
       genders file indicated by filename (or the default genders file if filename is NULL).

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.
