POSIX Signals, C and C++

Occasionally folks are unaware of or misunderstand the rules on writing POSIX signal handlers in C and C++. So I've written a brief overview of POSIX signal handling pitfalls. Corrections and suggestions welcome.

When viewing the binary representation of a file I prefer to use a format I first saw in a utility provided by IBM in OS360 in 1964. So I wrote C code I call hxdump that prepares output in a similar format. Download the hxdump.c C source. To compile it cc -g hxdump.c -o hxdump should suffice. The source has always said there are no restrictions on its use.

Sometimes (rarely) one has a file one wants to patch directly, rather than use an editor. Years ago I wrote (and made available via ftp) a program I call binpatch. Download the binpatch.c C source. To compile it cc -g binpatch.c -o binpatch should suffice. The source has always said there are no restrictions on its use.

Also, see the palm extractor (C code).
