Thank you for quick response. Unfortunately this isn't the solution for my
problem because channel is set for nonblocking few lines before code i
pasted using
libssh2_channel_set_blocking(channel, 0);
also there i use function
libssh2_channel_handle_extended_data2(channel,
LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE);
but i don't suppose that it have influence on my problem.
