Today, I started thinking about inode structure passed in "open" call to device drivers in linux. I have religiously used "inode->i_rdev" for major and minor numbers before. But I never used it for any other purpose. ( Most probably I never went past my toy drivers.)
So, I was wondering if some one can explain any other usage of this structure inside device driver.
Hi,
For one of the project which i am working on i need to write a cpp code such that it will create the structure dynamically instead of reading it from header file.
For example we have a program which is reading a binary file according to the structure mentioned in header file.
But we want to make the program to generic to support reading of binary file of any structure that we pass to it
I am attempting to modify the bio structure (in bio.h) for linux-3.2.0 (running Ubuntu). The only thing I need to do to this structure is to add an additional variable to keep track of an integer variable (it is for a tainting algorithm).
I need to keep millions of files on an ext4 system.
I understand that having a structure with multiple subdirectories is the general accepted solution.

they defined a structure superio_struct and initialized as
Code:
superios[NR_SUPERIOS] = { {0,},};
I am not able to understand above initialization has what is it getting initialized to.
What I deduce till now is superios is a structure array of struct superio_struct
and NR_SUPERIOS is defined as 3 hence an array of structure
I have a simple question about passing character pointers through sockets.
example code/data
Code:
struct mystr
{
unsigned int one;
unsigned two two;
char *ch;
};
unsigned int strsize;//character array size
I want to organize my photos as follows:
my own folder structure, not date-based
not in ~/Pictures
automatically detect new photos in my folder structure (including in subfolders)
do not create copies of the photos (I need the harddrive space!)
Is this possible with Shotwell, and how do I do it? I really don't want Shotwell to move my files around.
OK, I know, this is the epitome of laziness.
Is there somewhere where I can see the file structure of a fresh install of testing?
I'm pretty green around the ears and too lazy to use mc and a pencil to map it out.
Thanks,
JP.
P.S.: Oops, guess I need to update my sig.

I'm new to socketpairs and I need my children each to pass information from a structure to the parent.I was told this can be done using SOCK_DGRAM but I don't know how to do it.I looked over the internet but i couldn't find a concrete example.Can you please show for example hoe can you pass to the parent a structure made out of 2 ints and a string maybe ?I just want an example so I can understand
