NAME

       snd_rawmidi_receive - receive the input data from the device

SYNOPSIS

       int snd_rawmidi_receive(struct snd_rawmidi_substream * substream, const unsigned char * buffer, int count);

ARGUMENTS

       substream
	   the rawmidi substream

       buffer
	   the buffer pointer

       count
	   the data size to read

DESCRIPTION

       Reads the data from the internal buffer.

RETURN

       The size of read data, or a negative error code on failure.

NAME

       libssh2_channel_write_ex - write data to a channel stream blocking

SYNOPSIS

       #include <libssh2.h>

       ssize_t libssh2_channel_write_ex(LIBSSH2_CHANNEL *channel,
					int stream_id, char *buf,
					size_t buflen);

DESCRIPTION

       Write data to a channel stream. All channel streams have one standard I/O substream (stream_id == 0), and may have up to 2^32 extended data
       streams as identified by the selected stream_id. The SSH2 protocol currently defines a stream ID of 1 to be the stderr substream.

       channel - active channel stream to write to.

       stream_id - substream ID number (e.g. 0 or SSH_EXTENDED_DATA_STDERR)

       buf - pointer to buffer to write

       buflen - size of the data to write

       libssh2_channel_write(3) and libssh2_channel_write_stderr(3) are convenience macros for this function.

       libssh2_channel_write_ex(3) will use as much as possible of the buffer and put it into a single SSH protocol packet. This means that to get
       maximum performance when sending larger files, you should try to always pass in at least 32K of data to this function.

RETURN VALUE

       Actual number of bytes written or negative on failure.  LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
       negative number, it isn't really a failure per se.

ERRORS

       LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_CHANNEL_CLOSED - The channel has been closed.

       LIBSSH2_ERROR_CHANNEL_EOF_SENT - The channel has been requested to be closed.
