# libssh2\_channel\_receive\_window\_adjust2(3)

adjust the channel window

## NAME

libssh2\_channel\_receive\_window\_adjust2 - adjust the channel window

## SYNOPSIS

```
#include <libssh2.h>
int
libssh2_channel_receive_window_adjust2(LIBSSH2_CHANNEL * channel,
                                       unsigned long adjustment,
                                       unsigned char force,
                                       unsigned int *window);
```

## DESCRIPTION

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 VALUE

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.

## ERRORS

## AVAILABILITY

Added in libssh2 1.1 since the previous API has deficiencies.
