MINOR: tools: provide a may_access() function and make dump_hex() use it
It's a bit too easy to crash by accident when using dump_hex() on any area. Let's have a function to check if the memory may safely be read first. This one abuses the stat() syscall checking if it returns EFAULT or not, in which case it means we're not allowed to read from there. In other situations it may return other codes or even a success if the area pointed to by the file exists. It's important not to abuse it though and as such it's tested only once per output line.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
