Function accessZ [src]
Same as access except path is null-terminated.
Prototype
pub fn accessZ(path: [*:0]const u8, mode: u32) AccessError!void Parameters
path: [*:0]const u8mode: u32 Possible Errors
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/
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.
