[boost] [filesystem] truncate() function?

There was a request on the users list for a file truncate() function 
similar to the POSIX function of the same name. Since Windows provides a 
function with virtually identical semantics, this seems like a 
reasonable request.

The POSIX spec includes:

"If the request would cause the file size to exceed the soft file size 
limit for the process, the request shall fail and the implementation 
shall generate the SIGXFSZ signal for the process."

I have no knowledge of or experience with POSIX signals, so need advice.

Does the POSIX implementation need to do anything to cope with the 
possibility of a SIGXFSZ signal? If so what?

Thanks,
