Re: 'break' system call man page is missing?
In /usr/include/sys/syscall.h it's listed as SYS_break with the number 17. Is it the same as brk(2)?

In the mean time in one case it fails for me with errno=22 (Invalid argument). Is it's argument (pointer) related to /proc/##/map? One of the blocks mentioned in this map file has upper limit equal to the argument pointer of break.

Re: 'break' system call man page is missing?
What is the condition when errno=22 is returned? I figured this out myself by looking into the kernel source code. But there still should be a man page for this since this seems to be only (or at least one of the very few) system calls w/out documentation.

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 loop(s) 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 sh shell. So, do you mean some other kind of break command in some other context? -- Lars Eighner http://www.larseighner.com/index.html 8800 N IH35 APT 1191 AUSTIN TX 78753-5266 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
