* If the callee is also interested in the references which are

* FUNCTION
* Advanced popen() with additional parameters:

* - login shell if wanted
* - user under which to start (for root only)
* - stdin and stderr file pointers
* - wait for exactly the process we started
* File descriptors have to be closed with sge_peclose().
*
* This function is reentrant as long as env is not provided to

*
* INPUTS
* const char *shell - which shell to use
* int login_shell - make it a login shell?
* const char *command - name of the program
* const char *user - user under which to start (for root only)
* char **env - env variables to add to child
* FILE **fp_in - file input stream
* FILE **fp_out - file output stream

*
* RESULT
* pid_t - process id
*
* NOTES
* MT-NOTE: sge_peopen() is MT safe
*
* DO NOT ADD ASYNC SIGNAL UNSAFE FUNCTIONS BETWEEN FORK AND EXEC

* NAME
* sge_gdi_packet_pack_task() -- pack a single GDI task
*
* SYNOPSIS
* bool
* sge_gdi_packet_pack_task(sge_gdi_packet_class_t * packet,
* sge_gdi_task_class_t * task,
* lList **answer_list,
* sge_pack_buffer *pb)
*
* FUNCTION
* This functions packs all data representing one GDI request
* of a mutli GDI request (represented by "packet" and "task")
* into "pb". Errors will be reported with a corresponding
* "answer_list" message and a negative return value.
*
* "pb" has to be initialized before this function is called.
* init_packbuffer() or a similar function has do be used to
* initialize this "pb". The function sge_gdi_packet_get_pb_size()
* might be used to calculate the maximum size as if the buffer
* would be needed to pack all tasks of a multi GDI request.
* Using this size as initial size for the "pb"
* will prevent continuous reallocation of memory in this
* function.
*
* INPUTS
* sge_gdi_packet_class_t * packet - GDI packet
* sge_gdi_task_class_t * task - GDI task
* lList **answer_list - answer_list
* sge_pack_buffer *pb - packing buffer
*
* RESULT
* bool - error state
* true - success
* false - failure
*
* NOTES
* MT-NOTE: sge_gdi_packet_pack_task() is MT safe
*
* SEE ALSO
* gdi/request_internal/sge_gdi_packet_get_pb_size()
