function call bracketed numbers
 

Please, can someone tell me what the number '2' refers to in function calls, for example fork(2).

Man can

The '2' is an argument or parameter, every function is different so you need to look up the documentation.

Just had a thought... if you saw 'fork(2)' somewhere, it may be a reference to the fork man pages - section 2

eg.

'man 2 fork'
