Receive Text up to a Delimiter Byte

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringUntilByte, which receives bytes until a specific raw byte value is found, then decodes the preceding bytes using StringCharset. The delimiter is excluded from the returned string.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const socket = try chilkat.Socket.init();
    defer socket.deinit();

    // Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
    // connection succeeds; the 4th is the maximum time to wait, in milliseconds.
    const b_tls = true;
    const max_wait_ms = 5000;
    socket.connect("example.com", 5000, b_tls, max_wait_ms) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    // StringCharset controls the character encoding used when sending and receiving text.
    socket.setStringCharset("utf-8");
    // Send a request using a simple application-defined text protocol in which each message ends with a
    // CRLF.
    const command = "STATUS\r\n";
    socket.sendString(command) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    // Receive bytes until a specific raw byte value is found, then decode the preceding bytes using
    // StringCharset.  The delimiter itself is excluded from the returned string.  Here the delimiter is
    // the linefeed byte (decimal 10).
    const line = socket.receiveStringUntilByte(alloc, 10) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("{s}\n", .{line});
