Given a username, is there an easy way to convert this to a uid in c/c++. I would hope not to have to look at /etc/passwd?
Thanks

I am not using it, this library is.
http://www.ossp.org/pkg/lib/uuid/
I can modify the library, but the solution must be extremely portable.
I have found online evidence that suggest that srandom is not thread safe. I am unable to proove this because I don't know if this was fixed in recent years. Do you know whether this thread safety...
Due to C++'s ability to overload functions, if
d1s->getX()+1 and
d1s->getY() +1
are types convertable to ints, the compiler should know to call the two parameter function with type ints.
you could look into signals maybe in linux. They might be useful.
As many characters that will fit with the attatched '\0' put at the end of the buffer.
Just Clarifying.
What are you trying to do and I can tell you if that code is necessary or not.
I don't think that there is a way to tell what file descriptor is available for io, but you might want to look into the select function. This function comes in handy when working with sockets, so...
What do you want to know about sigio? It is sent to a program when io has become possible. You may want to setup a signal handler using signal(), sigaction(), etc.
fcntl() man page
so...
Why would you want to do this? You can not make up an address to assign a variable to. You can make a pointer and then make it point to an address. If you could pick the address off a variable,...
Sorry, I didn't read the whole thread, I just saw that stormtrooper said that argv[0] = program.exe
Not sure if I remember right, but I don't think argv[0] is guarenteed to be the program name.

-good luck
That won't give the simplified answer though 0rion. To do that you need to look up gcm algorithms.
The reason people forget to add the -lm when using the math library is because they think it is part of the standard. Well it is, but they decided to link the c library automatically to all...
You have to link with the math library.
gcc -o blah blah.c -lm
I am on the chess team at school, I would be willing to play, but I prefer longer games than 5/3, mabey aroudn 15 minutes or 10, but more than five. That is too fast, doesn't create tactically...
Yeah, Salem is right, if you want the most accurate timing, you need to write a kernel driver, that deals with the times instead, then it can call tasklet. But to change a user process's priority,...
You need to give name some room to point to. Like this
t-> name = malloc(512 * sizeof(char));
/* then */
strcpy(t->name, "robot name");
then strlen() should work and printing it will too. Be...
What do you consider important?
Use sockets to try and make a connec()tion to an outside server. You could I guess check to see if they have everything set up for internet, but that doesn't mean it is going to work, so you will...
you don't need the & when you are scanning into arrays, you might want to start looking into fgets http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1044652485&id=1043284385
Then you might...
search the boards for both of those answers then ask again
Well, if you network cable is plugged in, you should have a connection, right? So just ping something, get the result, and point your symlinks accordingly.
Well, assuming you know shell scripting, because I don't, you could do this. When you plug in your network card (wireless one), a device is created in /dev right? So check to see if that device...
