An fhandler is a file type handler. This is where the unix device
emulation happens.
hinfo.cc maps posix file descriptors to a table of file handlers (type
dtable.cc maps posix file descriptors to a table of file handlers (type
fhandler) in the dll. It's mostly concerned with managing the table
of descriptors (open, dup, fork, select). Most of the posix I/O
system calls (syscalls.cc) use the hinfo table to call the right
system calls (syscalls.cc) use the fdtab table to call the right
fhandler directly.
fhandler.cc is the base class; specific types are derived as
appropriate (see fhandler.h). hinfo.cc is in charge of selecting and
appropriate (see fhandler.h). dtable.cc is in charge of selecting and
creating a suitable fhandler when you open a file. path.cc handles
emulated files in /dev (like /dev/null) by returning an FH_* value
from get_device_number (which hinfo.cc calls in hinfo::build_fhandler).
from get_device_number (which dtable.cc calls in dtable::build_fhandler).
Note: if you're looking for read() and write(), they call _read() and
_write() in syscalls.cc. The non-underscored ones are in
