could someone please, show me how to make a hard link to a file in c language ?
i am using minix. The program below reads the last number from file numbers, adds a one to it and then appends the new number into the file. I use a c script as driver to this program, the c script has 6 processors of this program. the processors read and write into the numbers file at the same time, causing disoder in the numbers file. so in order to put some order into this chaos, i want to use a hard link to the file numbers, which will prevent other processors to access the file when it is being used by onother processor.
But the way i am using link isn't working, can someone help ?
I am sorry for the lack of documentation in the code

Someone asked me a question today about the difference between a hard link and a soft link. That got me thinking and maybe someone can answer.
Why would I ever use a hard link if I can use a soft link instead? (2 Replies)
Hi all!
I'd like to know the differences between hard links and soft links. I've already read the ln manpage, but i'm not quite sure of what i understood.
Does a hard link sort of copy the file to a new name, give it the same inode number and same rights?
What exactly should I do to do this:... (3 Replies)
