How can i use system calls in my module ?
Do i need any headers file ?
When i try to use for example write() or sys_write()
durring compilation i receive error that these symbols are not defined.
My problem is that i'm using 2.6 kernel and i do not have
/proc/ksyms. So where can i find which symbols are exported by my kernel ?
By the way: Where in linux source code is open() system call ?
