int libssh2_channel_receive_window_adjust2(LIBSSH2_CHANNEL * channel,
unsigned long adjustment,
unsigned char force,
unsigned int *window);
Adjust the receive window for a channel by adjustment bytes. If the amount to be adjusted is less than LIBSSH2_CHANNEL_MINADJUST and force is 0 the adjustment amount will be queued for a later packet.
This function stores the new size of the receive window (as understood by remote end) in the variable 'window' points to.
Return 0 on success and a negative value on error. If used in non-blocking mode it will return LIBSSH2_ERROR_EAGAIN when it would otherwise block.
Added in libssh2 1.1 since the previous API has deficiencies.
