libssh2_channel_set_blocking – set or clear blocking mode on channel
Synopsis
#include <libssh2.h> void libssh2_channel_set_blocking(LIBSSH2_CHANNEL *channel, int blocking);
Description
channel – channel stream to set or clean blocking status on.blocking – Set to a non-zero value to make the channel block, or zero to make it non-blocking.
Currently this is just a short cut call to libssh2_session_set_blocking(3) and therefore will affect the session and all channels.
