Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String

May 3, 2011

I'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.

Programming :: C - Put A Specific Arbitrary Part Of A String Into It's Own String?

Apr 18, 2010

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.

Ubuntu :: After Upgrade To Lucid Getting Warnings - Can't Convert String

Jun 24, 2010

After upgrading to Lucid I get the following warnings which I did not have before:

Warning: Cannot convert string "-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*" to type FontStruct
Warning: Cannot convert string "-*-helvetica-medium-r-*--*-120-*-*-*-*-iso8859-1" to type FontStruct

These occur when I start emacs and xpdf. On searching I see people are adding font paths to their xorg.conf file but on looking at mine there is no longer a font section. Also I have few directories fonts/X11/usr/share/fonts/X11$ ls misc/util/. I'm assuming the above folders and xorg.conf file are correct.

Programming :: Double Data Type Mantissa?

Nov 23, 2010

in c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)
