.SH DESCRIPTION
|
||
|
|
\fIsession\fP - Session instance as returned by
|
||
|
|
.BR libssh2_session_init_ex(3)
|
||
|
|
|
||
|
|
\fIusername\fP - Remote user name to authenticate as.
|
||
|
|
|
||
|
|
\fIusername_len\fP - Length of username.
|
||
|
|
|
||
|
|
\fIpublickeydata\fP - Buffer containing the contents of a public key file.
|
||
|
|
|
||
|
|
\fIpublickeydata_len\fP - Length of public key data.
|
||
|
|
|
||
|
|
\fIprivatekeydata\fP - Buffer containing the contents of a private key file.
|
||
|
|
|
||
|

\fIprivatekeydata_len\fP - Length of private key data.
|
||
|

|
||
|

\fIpassphrase\fP - Passphrase to use when decoding private key file.
|
||
|
|
|
||
|
|
Attempt public key authentication using either a public key file or a PEM
|
||
|
|
encoded private key file stored in memory. When providing a private key, the
|
||
|
|
public key is automatically extracted from it. When providing both, the
|
||
|
|
passed public key takes precedence.
|
||
|
|
.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

||
|
