/*!
|
|
* Higher-level interfaces to libc::* functions and operating system services.
|
|
*
|
|
* In general these take and return rust types, use rust idioms (enums,
|
|
* closures, vectors) rather than C idioms, and do more extensive safety
|
|
* checks.
|
|
*
|
|
* This module is not meant to only contain 1:1 mappings to libc entries; any
|
|
* os-interface code that is reasonably useful and broadly applicable can go
|
|
* here. Including utility routines that merely build on other os code.
|
|
*
|
|
* We assume the general case is that users do not care, and do not want to
|
|
* be made to care, which operating system they are on. While they may want
|
|
* to special case various special cases -- and so we will not _hide_ the
|
|
* facts of which OS the user is on -- they should be given the opportunity
|
|
* to write OS-ignorant code by default.
