Function mkdirat [src]
On Windows, sub_dir_path should be encoded as WTF-8.
On WASI, sub_dir_path should be encoded as valid UTF-8.
On other platforms, sub_dir_path is an opaque sequence of bytes with no particular encoding.
Prototype
pub fn mkdirat(dir_fd: fd_t, sub_dir_path: []const u8, mode: mode_t) MakeDirError!void Parameters
dir_fd: fd_tsub_dir_path: []const u8mode: mode_t Possible Errors
In WASI, this error may occur when the file descriptor does not hold the required rights to create a new directory relative to it.
WASI-only; file paths must be valid UTF-8.
Windows-only; file paths provided by the user must be valid WTF-8. https://simonsapin.github.io/wtf-8/
On Windows, \\server or \\server\share was not found.
The Operating System returned an undocumented error code.
This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.
When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.
