Programming :: Script For Executing A Program And Doing String Comparison
May 6, 2009I am fairly new to linux still and I'm currently trying to write a shell script (which I have never done) that is supposed to run the xrestop(like top) program. What I want to do is execute the program and check the identifier column to see if a certain program is running. If it is running I want to strip the data from that row of the terminal say every 5 seconds or so and put it in a text file. Is this going to be a complicated thing?
Heres a list of the columns when you run xrestop program res-base Wins GCs Fnts Pxms Misc PxmMem Other Total PID Identifier.

May 3, 2011I'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.

Feb 9, 2010I'm looking at a new board that supports both DDR2 800 and DDR2 667. But, the FSB is only 667MHz. My question is: is there a benefit of using the DDR2 800 on the 667 FSB? That is, can the DDR2 800 be fully utilized on this system? What are pros and cons of such? Does the added benefit outweigh the additional cost of the RAM?
Note: I'm not looking to overclock at all, and this is not going to be used for 3D apps (games or video editing).

Programming :: Operator For Floating Point Comparison?
May 10, 2011I know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.
