NAME

       snd_rawmidi_transmit_ack - acknowledge the transmission

SYNOPSIS

       int snd_rawmidi_transmit_ack(struct snd_rawmidi_substream * substream, int count);

ARGUMENTS

       substream
	   the rawmidi substream

       count
	   the tranferred count

DESCRIPTION

       Advances the hardware pointer for the internal output buffer with the given size and updates the condition. Call after the transmission is
       finished.

RETURN

       The advanced size if successful, or a negative error code on failure.

NAME

       libssh2_channel_read_ex - read data from a channel stream

SYNOPSIS

       #include <libssh2.h>

       ssize_t libssh2_channel_read_ex(LIBSSH2_CHANNEL *channel, int stream_id, char *buf, size_t buflen);

       ssize_t libssh2_channel_read(LIBSSH2_CHANNEL *channel, char *buf, size_t buflen);

       ssize_t libssh2_channel_read_stderr(LIBSSH2_CHANNEL *channel, char *buf, size_t buflen);

DESCRIPTION

       Attempt	to  read data from an active 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 read from.

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

       buf - pointer to storage buffer to read data into

       buflen - size of the buf storage

       libssh2_channel_read(3) and libssh2_channel_read_stderr(3) are macros.

RETURN VALUE

       Actual  number  of  bytes  read	or  negative  on  failure.  It	returns  LIBSSH2_ERROR_EAGAIN  when  it  would otherwise block. While LIB-
       SSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.

       Note that a return value of zero (0) can in fact be a legitimate value and only signals that no payload data was read. It is not an error.

ERRORS

       LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.

       LIBSSH2_ERROR_CHANNEL_CLOSED - The channel has been closed.
