write_response_head

write_response_head :: (
    out: *[..] u8,
    status: int,
    headers: [] Header_Field,
    body_length: s64,
    options := Response_Options.{}
) -> (Body_Kind, bool)

Appends a response head and returns how the body must be sent (see write_request_head). body_length is the length of the body the response is for; for a HEAD response (set request_method) it only fills in Content-Length, and nothing may be sent after the head. 1xx, 204 and CONNECT 2xx responses get no framing headers. A length of -1 means unknown: chunked on HTTP/1.1, and for HTTP/1.0 the body ends when the connection closes (Connection: close is added and the caller must close).

Parameters

out: *[..] u8

the buffer the head is appended to.

status: int

the status code.

headers: [] Header_Field

sent as given. Framing headers are added for you, so passing one is an error.

body_length: s64

the body size in bytes, 0 for none, or -1 when it is not known yet.

options := Response_Options.{}

version, reason phrase, request method, keep-alive, and the Date and Server values.

Returns

Body_Kind

bool
