/****** qmaster/sge_mod_configuration() ****************************************
* NAME
* sge_mod_configuration() -- modify cluster configuration
*
* SYNOPSIS
* int sge_mod_configuration(lListElem *aConf, lList **anAnswer, char *aUser,
* char *aHost)
*
* FUNCTION
* Modify cluster configuration. 'confp' is a pointer to a 'CONF_Type' list
* element and does contain the modified configuration entry. Adding a new
* configuration entry is also viewed as a modification.
*
* INPUTS
* lListElem *aConf - CONF_Type element containing the modified conf
* lList **anAnswer - answer list
* char *aUser - target user
* char *aHost - target host
*
* RESULT
* int - 0 success
* -1 error
*
* NOTES
* MT-NOTE: sge_mod_configuration() is MT safe
*
