Other exceptions, however, the kernel cannot process intelligently and it must instead defer the exception handling operation to the faulting process. My diferrential backups are fine. Multiple outputs The tee command writes to multiple outputs which doesn't map well to the implicit handling of SIGPIPE on any particular output. deer in German: Hirsch, Reh Integer function which takes every value infinitely often How does template argument deduction work when an overloaded function is involved as an argument?

POSIX signals The list below documents the signals specified in the Single Unix Specification. Sigpipe Signal In Linux Ctrl-Z sends a TSTP signal ("terminal stop", SIGTSTP); by default, this causes the process to suspend execution. Miscellaneous signals The following signals are not specified in the POSIX specification. Retrieved 21 September 2013. ^ "Proper handling of SIGINT and SIGQUIT".

If you are using buffered TCPIP, then a successful write just means your data has been queued to send, it doesn't mean it has been sent. For example, SIGPIPE will be generated when a process writes to a pipe which has been closed by the reader; by default, this causes the process to terminate, which is convenient Note that not all operating systems support the MSG_NOSIGNAL flag. current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list.

POSIX system call specification. This article needs additional citations for verification. Typing certain key combinations at the controlling terminal of a running process causes the system to send it certain signals: Ctrl-C (in older Unixes, DEL) sends an INT signal ("interrupt", SIGINT); It's been awhile since I've seen this. –Sam Oct 3 '13 at 14:36 add a comment| up vote 11 down vote You cannot prevent the process on the far end of
SIGLOST The SIGLOST signal is sent to a process when a file lock is lost. Sigpipe Ios In practice, this kind of signal is rarely encountered since applications rely on libraries (e.g. You can hack things to get equivalent behavior in simple pipelines though.
Macro: int SIGXCPU CPU time limit exceeded. However, people ignoring return codes in C is a much wider issue than just write() calls. You need to select on the read bits. Python Sigpipe SIGVTALRM n/a Terminate Virtual timer expired.
Retrieved 8 February 2013. ^ "getrlimit, setrlimit - control maximum resource consumption". On GNU/Hurd systems, SIGLOST is generated when any server program dies unexpectedly. It was originally designed to notify the process of a serial line drop (a hangup). SIGSTOP n/a Stop Stop executing (cannot be caught or ignored).
