A Bytecode Alliance project
posish
provides safe wrappers to POSIX-ish libc
APIs and syscalls.
posish
is focused on functionality that isn't already provided by std
or other low-level crates such as getrandom
and errno
. It prioritizes
safe interfaces, including considering raw file descriptors to be equivalent
to pointers in terms of making APIs unsafe, in the spirit of
std::os::unix::io::FromRawFd::from_raw_fd
being unsafe and
RawFd
not implementing AsRawFd
/IntoRawFd
.
posish
is relatively low-level and does not support Windows; for higher-level
and portable APIs to this functionality, see the system-interface
,
cap-std
, and fs-set-times
crates.
