Try Ctrl-D

In a C program it's a implementation defined constant for stdio functions. For system calls it is 0 on linux.

C returns EOF as -1 decimal or 0xFFFFFFFF hex. In a shell, CTRL-D issues a EOF character.

What the hell was I thinking when I said system calls return 0 on error?
Pfffft /me puts the crack pipe down.

For standard i/o functions do you really want to rely on -1 being EOF? I always compare the return value against EOF, which depending on implementation is not necessarily -1.

Well he asked what the EOF return value was in linux, and it is defined as (-1) in the linux standard headers.

I guess I've been reading too much comp.lang.c
