Function access [src]
check user's permissions for a file
On Windows, asserts path is valid WTF-8.
On WASI, invalid UTF-8 passed to path causes error.InvalidUtf8.
On other platforms, path is an opaque sequence of bytes with no particular encoding.
On Windows, mode is ignored. This is a POSIX API that is only partially supported by
Windows. See fs for the cross-platform file system API.
Prototype
pub fn access(path: []const u8, mode: u32) AccessError!void Parameters
path: []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.
