.SH DESCRIPTION
|
|
\fIchannel\fP - Previously opened channel instance such as returned by
|
|
.BR libssh2_channel_open_ex(3)
|
|
|
|
\fIvarname\fP - Name of environment variable to set on the remote
|
|
channel instance.
|
|
|
|
\fIvarname_len\fP - Length of passed varname parameter.
|
|
|
|
\fIvalue\fP - Value to set varname to.
|
|
|
|
\fIvalue_len\fP - Length of value parameter.
|
|
|
|
Set an environment variable in the remote channel's process space. Note that
|
|
this does not make sense for all channel types and may be ignored by the
|
|
server despite returning success.
|
|
.SH 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.
|
|
|
|
.SH ERRORS
|
|
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
