@defun access-file filename string
@vindex remote-file-name-access-timeout
If you can read @var{filename} this function returns @code{nil};
otherwise it signals an error
using @var{string} as the error message text.
If the user option @code{remote-file-name-access-timeout} is a number,
the function signals an error when it doesn't finish after that time
(in seconds). This applies only to remote files, and only when there
is no additional time spent while reading passwords or alike.

@value{tramp} blocks Emacs at startup
@vindex remote-file-name-access-timeout
Some packages, like @file{desktop.el} or @file{recentf.el}, access
remote files when loaded. If the respective file is not accessible,
@value{tramp} could block. In order to check whether this could
happen, add a test via @code{access-file} with a proper timeout prior
loading these packages:
@lisp
@group
(let ((remote-file-name-access-timeout 10))
(access-file "@file{@trampfn{method,user@@host,/path/to/file}}" "error"))
@result{} nil
@end group
@end lisp
The result @code{nil} means success. If the file is not accessible,
or if the underlying operations last too long, @code{access-file}
returns with an error.
The value of the timeout (10 seconds in the example) depends on your
preference and on the quality of the connection to the remote host.
If the connection to the remote host isn't established yet, and if
this requires an interactive password, the timeout check doesn't work
properly.

Does @value{tramp} support @acronym{SSH} security keys?

/* The MSVC prep program generates a ._xe file from .exe, where relevant
function calls etc have been patched to go through thunks (generated
by prep) that record timing/call information. Because the thunks
need to make references to functions imported from profile.dll, the
import table must be expanded; the end result is that all the
sections following .rdata are relocated to higher RVAs (add a final
code section is added holding all the thunks). The .reloc section is
also expanded, so that the thunks themselves are relocatable.
It is this relocation which kills emacs._xe, because the dumped heap
pointers aren't relocated, because there is no relocation data for
either the relevant global/static variables or the heap section
itself, both of which contain pointers into the heap. [Note that
static variables which aren't initialized during linking may become
initialized with heap pointers, or even pointers to other static
variables, because of dumping.]
We could potentially generate the relocation data ourselves by making
two versions of temacs, one with an extra dummy section before
EMHEAP to offset it, and then compare the dumped executables from
both. That is a lot of work though, and it doesn't solve the problem
of dumped pointers to static variables, which also can be relocated.
A better solution is to pre-process emacs.exe so that the .rdata and
.reloc sections are moved to the end of the section table, and thus
prep won't relocate anything else. (Of course, we leave "dead"
copies of these two sections in place, so that the virtual address of
everything else is unaffected.) Relocating the .reloc data is
trivial - we just update the IMAGE_BASE_RELOCATION address in the
header (the data itself doesn't change). Relocating the import table
is more complicated though, because the calls to imported functions
must be patched up. That requires us to selectively apply the base
relocations when we encounter references to imported functions (or
variables) in other sections, but at least the base relocations are
easy to parse. */
