Programming :: Set A Recursive Function As Inline?
Feb 3, 2011Is it good to set a recursive function as inline? I would think it would increase the performance speed of the program.

Programming :: What Is Static Inline Void Tvec_base
Aug 27, 2010I was going through a file known as linux-2.6.34/kernel/timer.c and found following code.
static inline void
timer_set_base(struct timer_list *timer, struct tvec_base *new_base)
{
timer->base = (struct tvec_base *)((unsigned long)(new_base) |
tbase_get_deferrable(timer->base));
}
I want to understand what is it doing. What is the meaning of static inline in above? I searched and came across

Programming :: GCC Inline Assembler Doesn't Even Support Local Variable?

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?
May 18, 2010I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

Feb 16, 2011This is my sub;
Code:
sub projName

print "Enter project name: " ;
$PROJ = <STDIN>;

I can call this routine and it works fine when I enter a valid name for $PROJ. If I enter an invalid name it goes to the else block and prints the statement. However, it does not call itself. Instead the script just exits.I've googled 'perl recursive subroutines' and the example don't appear to be doing anything different.
Programming :: Recursive Search In A Tar.bz2 File?
Jul 14, 2011I am looking for a one liner to search for a string in file(s) which are in a tar ball (.tar.bz2 in my case)

Programming :: Make Recursive Makefile Work?
Jun 8, 2011I'm trying to make recursive makefile work but it's giving me two problems. I have a top folder with the main Makefile and one Makefile for each sub folder 'one' and 'two'. Makefile in subfolder 'one' and 'two' are identical. The top Makefile (still a bit messy) looking like this:

CFLAGS = -Wall -Wextra

Programming :: Compiling Recursive Makefile In Directory Structure
May 18, 2011I'm having problems with compiling recursive Makefiles in my directory structure:
My folder layout is:
top/|- one/|- one.c (With main function)|- zero.c|- two/|- two.cin my top folder the make file looks like:
Code:
MAKE_DIRECTORIES = one two
.PHONY: all
all: $(MAKE_DIRECTORIES)
.PHONY: $(MAKE_DIRECTORIES)
$(MAKE_DIRECTORIES):
@echo $@
$(MAKE) --directory=$@
in my one and two folder I have the following Makefile:
Code:
.PHONE: all
all:
@echo $@
$(CC) $(CFLAGS) *.c
But when I compile it from top folder: make
I get following output:
Code:
one
two
Which states that directory statement by echo in main Makefile is ok but the files are not compiled in one and two.

Programming :: Test Permissions On All Files / Folders Into A Folder Recursive?
May 16, 2010Way to test permissions on all files/folders into a folder recursive, then if those are not user:user then do :
Code:
chown user:user thatconcernedfile
The problem with that
Code:
chown user:user -R /folder
is that it is doing changes on file permissions whihch are already ok. If you wanna maintain a specific permission on a folder this is really not good this :
Code:
while [ 1 ] ; do
chown user:user -R /folder
# /folder contains 6.0 Tb
sleep 2s
done
Programming :: Bash - Recursive Find - Create Parent Folder - Moving File
Dec 5, 2010I'm starting bash shell script and I'm looping without any solution.
I'm trying to find some files under a folder hierarchy and in case of errors moving these files to a destination folder under the same hierarchy recreating this hierarchy if not exists.
Finding all ._* files under /src and moving them to /dest recreating folder1 or the others which contains ._* files but without moving files which does not correspond to the pattern.
Code:
I tried find command and I'am getting all needed files
Code:
But I don't know how to use the output to get the parent folder of files which are found to
1- create folder with mkdir -p /dest/folder1 or /dest/folder1/folder4
2- move found files from /src/... to /dest/... with rm command
I'm working on a find command as this trying to do all in the same line but ... little lost

Programming :: HTML5 "details" Tag Display - Inline - Display - Hidden CSS Ignored - Firefox - Seamonkey
Jan 11, 2011I'm testing HTML5 for the first time, using Firefox (beta) 4.0b8 and SeaMonkey (beta) 2.1b1, and its ignoring some CSS. Specifically, I have problems with the <details> tag. (It is nested in a paragraph...I am using it to provide an in-paragraph definition in hopes it can be toggled.)
Firefox only partly supports <details>. It's not supposed to show anything except the content of <summary>, unless you click on <summary>'s content. Instead, it puts a line break before the content of <details>, splitting the paragraph in two peices (which looks silly), without the "closed/open" functionality.
So I tried using "display:inline" in my CSS, but that gets ignored. Just for fun, I also tried "display:hidden" (also ignored) and "display:none" (obeyed).
SeaMonkey doesn't doesn't do anything special with the content of <display>...but it also ignores the same CSS as Firefox.
The only thing I can do to support semantic design is apply "font-style:italic" to all <details> elements.
Granted, you might ask, "why bother using <details> at all. then?" Well, I would like to have <details> for the browsers that support it, with the "font-style:italic" to degrade the page nicely for those that don't (such as for SeaMonkey).
Does anyone know why "display:inline" and "display:hidden" get ignored?

OpenSUSE :: Kmail 1.13.6 ( KDE 4.6 ) Forwarding Inline Not Working?
May 19, 2011I am running opensuse11.4. When trying to forward emails I can only do so as attachment. When I click and hold to select the forward inline option I get an empty email - same as if I would have clicked new. The same happens when I place the inline button on to the toolbar. Is this a bug with Kmail or is there another setting to forward mail inline?
View 1 Replies View RelatedGeneral :: Cron Job Email - Log Report Attached Instead Of Being Sent Inline
Sep 20, 2010I am running a Cron job which mails the content of a log report every day. The problem is that the contents are sent as an attachment instead of as the body of the email. The strange thing is that if I run the instructions from the command line everything works fine, but if I do so from the Cron job the log report is attached instead of being sent inline.
The instruction I use is:
Code:
mail -s "logfile for cron" cron@example.com </var/log/cron-log
Following some advice I read on a blog I also tried this instruction in my Cron file, but the result is the same: it works fine from the command line, but attaches the report when run from Cron:
Code:
echo "Content-Type: text/plain;" | mail -s "logfile for cron" cron@example.com </var/log/cron-log
How to ensure the content of the log file is inline?
Software :: Insert An Image Inline With Mutt By Using Attach?
Jan 23, 2011I can insert an image inline with mutt by using attach, then using ctl+d to make the image appear inline. However, it appears below my signature. If anyone knows of a way to make the image appear above the signature, I'd be grateful for their input. (This is with mutt 1.5.21--usually sent from a Fedora 14 machine, but I haven't found the behavior to change with the platform.)
Unfortunately, it's necessary to do this at work, for a particular daily email. The workaround is to use Thunderbird for this particular email, but I'd much prefer to use mutt.
