Function mkdiratZ [src]
Same as mkdirat except the parameters are null-terminated.
Prototype
pub fn mkdiratZ(dir_fd: fd_t, sub_dir_path: [*:0]const u8, mode: mode_t) MakeDirError!void Parameters
dir_fd: fd_tsub_dir_path: [*:0]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.
