I'm reading Operating Systems in Depth by Thomas W. Doeppner, and I have a question about execl. He says it's called after fork(), and that it replaces the text (code) of the current process and replaces it with the code of the new program. But that doesn't make sense to me.
Does that mean... (4 Replies)

I am an Oracle DBA with some strange IO performance problems.
Between 04:00 and 06:00 AM local time each day I see a degrading of
IO performance (to a SAN).
I see that the AIX diagnostics seem to begin at 04:00.
Is it likely that AIX diagnostics might be affecting IO?

NAME
XltWorking - Convenience function to display a Working dialog, and update the bar graph in the dialog.
SYNOPSIS
#include <Xlt/Xlt.h>
Boolean XltWorking(widget, question, percent_done)
Widget widget;
String question;
int percentdone;
DESCRIPTION
XltWorking Creates a dialog containing a message string, a bar showing the percentage of the task complete, and an abort button. When
called with a percent_done value of zero the dialog is managed, and a timer installed to update the bar every second. If question is not
NULL, the message string in the dialog is set to this. When called with a percent_done of 100, the dialog is un-managed. If called with a
percent_done of -1, only the message is changed. Any value between 0 and 100 will cause the bar graph to be updated the next time the timer
fires, and processes any pending timer and X events. If the return value is True, the user has requested that the task should be aborted.
widget The widget to wait for.
question
The message to display in the working dialog. Or NULL, meaning no change.
percent_done
The percentage of the task complete. 0 will cause the dialog to be managed. 100 will cause the dialog to be un-managed. -1 will
update the question only. Any value between 0 and 100 will update the bar graph.
RETURN VALUE
Boolean, if True the abort button was pushed, or the window was closed by the window manager.
