stream_send_bytes :: Quanser C Functions

stream_send_bytes

Writes an array of bytes to the stream buffer.

Description

This function writes an array of bytes to the stream buffer. It is has the same semantics as the stream_send function.

Unlike the stream_send_byte_array function, this function does not require that the stream send buffer be at least num_elements bytes in length. Hence, it allows smaller stream buffers to be used.

Prototype

t_int
stream_send_bytes(t_stream stream, const t_byte * elements, t_uint num_elements);

Parameters

t_stream stream

A client stream established using stream_connect or stream_accept.

const t_byte * elements

The array to be sent.

t_uint num_elements

The number of elements in the array to send.

Return value

The number of bytes sent, which may be less than the request number of bytes for non-blocking streams. If an error occurs then a negative error code is returned.

Error codes

This function does not return any error code.
