I am not sure I know what you mean by "system call break."
There is an internal shell command "break" (as you should learn by entering
man break, which takes you to the builtins man page). There is no external
"break" command that I know of. Because it is an internal shell command, it
is documented in the man page for your shell, which in the case of "system"
in the c lib, is sh.
1) man break takes you to the builtin commands man page.
2) a table on that page tells you "break" is not an external command, but
is an internal command in csh and sh.
3) man system tells you system executes a command in an sh shell.
4) sh man tells you that break causes the end of execution of the innermost
or in other words, "break" is meaningless unless it is in a loop, which you
would be told in plain text if you entered "break" at the command line in an
