Function xn_line_put

Sends a line to the browser from a user-supplied Post or Get callback.

int xn_line_put(struct io_context * io_context, long wait, int type);

Parameters

io_context

I/O context passed to the user supplied callback.

wait

Number of seconds to wait for any previous sends to be acknowledged.

type

Flags for the operation to perform (PUT_QUE to queue the data and PUT_SEND to send all queued data).

return value

SOCKET_ERROR on error or a value >= 0 otherwise.

This function copies data in io_context->buffer to the output queue. The amount of data to be queued is specified by io_context->length. If there is not enough room in the output queue, the data already queued will be sent to the browser. When the callback function returns, any data queued will be sent.

Note that the maximum amount of data that can be sent with one call to this function is 1514 bytes, the size of the buffer pointed to by io_context->buffer.
