/****** sge_client_ijs/stop_ijs_server() ***************************************
* NAME
* stop_ijs_server() -- stops the commlib server for the builtin
* interactive job support
*
* SYNOPSIS
* int stop_ijs_server(COMM_HANDLE **phandle, dstring *p_err_msg)
*
* FUNCTION
* Stops the commlib server for the commlib connection between the shepherd
* of the interactive job (qrsh/qlogin) and the qrsh/qlogin command.
* Over this connectin the stdin/stdout/stderr input/output is transferred.
*
* INPUTS
* COMM_HANDLE **phandle - Pointer to the COMM server handle. Gets set to
* NULL in this function.
* dstring *p_err_msg - Contains the error reason in case of error.
*
* RESULT
* int - 0: OK
* 1: Invalid Parameter: phandle = NULL
* 2: General error shutting down the COMM server,
* see p_err_msg for details
*
* NOTES
* MT-NOTE: stop_ijs_server() is not MT safe
*
* SEE ALSO
* sge_client_ijs/start_ijs_server()
* sge_client_ijs/run_ijs_server()

*
* SYNOPSIS
* sge_tid_t sge_qexecve(const char *hostname, const char *queuename,
* const char *cwd, const lList *environment
* const lList *path_aliases)
*
* FUNCTION
* Starts a task in a tightly integrated job.
* Builds a job object describing the task,
* connects to the commd on the targeted execution host,
* deliveres the job object and waits for an answer.
* The answer from the execution daemon on the execution host
* contains a task id that is returned to the caller of the function.
*
* INPUTS
* const char *hostname - name of the host on which to start the task
* const lList *environment - list containing environment variable
* settings for the task that override the
* default environment
* const lList *path_aliases - optional a path alias list
*
* RESULT
* sge_tid_t - the task id, if the task can be executed,
* a value <= 0 indicates an error.
*
* NOTES
* MT-NOTE: sge_qexecve() is not MT safe
