# [DESCRIPTION](#DESCRIPTION)

*channel* - Previously opened channel instance such as returned by [**libssh2\_channel\_open\_ex(3)**](/man/os/libssh2/libssh2_channel_open_ex.3)

*term* - Terminal emulation (e.g. vt102, ansi, etc...)

*term\_len* - Length of term parameter

*modes* - Terminal mode modifier values

*modes\_len* - Length of modes parameter.

*width* - Width of pty in characters

*height* - Height of pty in characters

*width\_px* - Width of pty in pixels

*height\_px* - Height of pty in pixels

Request a PTY on an established channel. Note that this does not make sense for all channel types and may be ignored by the server despite returning success.

# [RETURN VALUE](#RETURN_VALUE)

Return 0 on success or negative on failure. It returns LIBSSH2\_ERROR\_EAGAIN when it would otherwise block. While LIBSSH2\_ERROR\_EAGAIN is a negative number, it is not really a failure per se.

# [ERRORS](#ERRORS)

*LIBSSH2\_ERROR\_ALLOC* - An internal memory allocation call failed.

*LIBSSH2\_ERROR\_SOCKET\_SEND* - Unable to send data on socket.

*LIBSSH2\_ERROR\_CHANNEL\_REQUEST\_DENIED* -
