Expand description
Prints to the standard error.
Similar to [std::eprint
], except it:
- Writes atomically, up to the greatest length supported on the platform.
- Doesn’t use locks (in userspace).
- Preserve libc’s
errno
and Windows’ last-error code value.
This allows it to be used to debug allocators, multi-threaded code, synchronization routines, startup code, and more.
