System calls are usually done by setting a certain register to a certain value and raising a certain interrupt, thus telling the kernel to do a certain thing to a certain different address.
Anything written as "certain ..." is different for each OS and sometimes even versions of the same OS. System calls are usually hidden behind the C library and should stay there, unless you want to start writing assembler code.
