.SH DESCRIPTION
|
||
|
|
A signal can be delivered to the remote process/service. Some servers or
|
||
|
|
systems may not implement signals, in which case they will probably ignore this
|
||
|
|
message.
|
||
|
|
|
||
|
|
\fIchannel\fP - Previously opened channel instance such as returned by
|
||
|
|
.BR libssh2_channel_open_ex(3)
|
||
|
|
|
||
|
|
\fIsigname\fP - The signal name is the same as the signal name constant, without the leading "SIG".
|
||
|
|
|
||
|
|
\fIsigname_len\fP - Length of passed signal name parameter.
|
||
|
|
|
||
|
|
There is also a macro \fIlibssh2_channel_signal(channel, signame)\fP that supplies the strlen of the signame.
|
||
|
|
.SH RETURN VALUE
|
||
|
|
Normal channel error codes.
|
||
|
