Function end [src]

Flushes any buffered data and sets the end position of the file. If not overwriting existing contents, then calling interface.flush directly is sufficient. Flush failure is handled by setting err so that it can be handled along with other write failures.

Prototype

pub fn end(w: *Writer) EndError!void

Parameters

w: *Writer

Possible Errors

AccessDenied TruncateError

FileBusy TruncateError

FileTooBig TruncateError

InputOutput TruncateError

NonResizable TruncateError

PermissionDenied TruncateError

Unexpected UnexpectedError

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.

WriteFailed Error

See the Writer implementation for detailed diagnostics.
