View 3 Replies View RelatedI've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
Is it possible to change permissions on symbolic links using the c programming language or any other for that matter? Now, I know what you are thinking, so let me provide some background.I know permission are meaningless. I know that typically permissions are set to 777.The project that I am working on does the following. On HPUX systems, a c binary recreates missing links from a stored image of the filesystem, if they are missing. The problem is that the permissions are 700 when the links are restored (should be 777). The c method to restore the symbolic links is "symlink()" which takes as its argument the target and linkname.The client wants 777 on the links. I do not know why the permissions are different. I would like to know if I can change permissions on the link by code, changing the mode?
Is this a bug somewhere in HPUX 10,x and 11.x os or "symlink" c library method, who knows?There are groups of nodes running HPUX, for example groupA, groupB etc.The problems appears in groupA but not in groupB. Seems the nodes are configured differently.While I would love to know if this is a configuration issue, it appears that way to me, there would be little I could do about it. Politics you know, but that's okay, in time someone would listen.

create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

View 4 Replies View RelatedI am faced with the following problem; I need to update all fields of type datetime without ... with the following sort data:01-01-2010 12:10:30.256 - this is just an example.these fields are restricted with a unique constrained. My question is how can I generate the above sort data, especially the last three numbers with leading point. After that how can I update a table with existing data with this newly generated data so that the fields really do carry unique data.As you probably can read out of my question, I read through the help in pgAdmin and came as far as generating date, maybe datetime but not the .123 number. And a little insert script I found in the help, that I modified as UPDATE resulted in updating only the last generated data in all required fields.

In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)

Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?
I am trying to remove the space between the 2nd and 3rd fields but just cannot work out how to do it. I've considered sed, cut, awk...I know with sed you can replace all instances within a file but can you also specify to remove, say, the 2nd instance of a space in each line (this would be perfect for me)?

I'd like to write a C/C++ program, that would grab content of window (in form of pixmap), which belongs to another application and do something with it. However, I ran into problems already at the beginning. In all toolkits I have searched through, I only found one function that claims to do what I want, namely XGetImage from Xlib. However, among other parameters like Display, coordinates, etc., it requires a Drawable. How do I specify a Drawable, that would correspond to the window I want to grab content of? Is there any easier way to achieve this?
