class unique_fd_impl

Defined at line 61 of file ../../third_party/android/platform/system/libbase/include/android-base/unique_fd.h

Container for a file descriptor that automatically closes the descriptor as

it goes out of scope.

unique_fd ufd(open("/some/path", "r"));

if (ufd.get() == -1) return error;

// Do something useful, possibly including 'return'.

return 0; // Descriptor is closed for you.

See also the Pipe()/Socketpair()/Fdopen()/Fdopendir() functions in this file

that provide interoperability with the libc functions with the same (but

lowercase) names.

unique_fd is also known as ScopedFd/ScopedFD/scoped_fd; mentioned here to help

you find this class if you're searching for one of those names.

unique_fd itself is a specialization of unique_fd_impl with a default closer.

int operator int ()

unique_fd's operator int is dangerous, but we have way too much code that

depends on it, so make this opt-in at first.
