I have a macro which I use with ROOT. In this macro I want to check if a part of string exist so I can ignore it inside a loop. So, inside a loop I want to have something like:
Code:
if (string == "pre_ti_data_bdt*" || string == "pre_ti_data_nn*")
continue;
but of course I cannot use * in this piece of code! How to do this trick in C++?
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.
I have the following two type of strings1: A/D2: A/C/DI am trying to write a subroutine to check whether all of the letters in string 1 appears in string 2. If yes, return true. If not, return false. In the above example, all the letters (A and D) in string 1 are also present in string 2, so I return true.

View 3 Replies View RelatedI'm not used to using "sed", but I need to use it to extract part of a string piped to it.
However, the "1" mentioned in the tutorials I read doesn't extract the token between the two brackets and returns the whole input string:
Code:
/tmp# echo "before [myfile.txt] after" | sed 's/[(.+)]/1/' before [myfile.txt] after
I expected simply "myfile.txt".

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.
