write_to_process

Writes data to the child's standard input and returns (success, bytes_written). It waits until the pipe has taken everything. It fails with the number of bytes that did go in when the pipe is closed, or the child has closed its end. Empty data succeeds with 0.

write_to_process :: (
    process: *Process,
    data: [] u8
) -> (success: bool, bytes_written: int)

process: Process;
assert(create_process(*process, "cmd.exe", "/c", "exit 0", capture_and_return_output = true));
defer deinit(*process);
ok, written := write_to_process(*process, .[]);
assert(ok && written == 0);
