| .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
 | |
| \fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
 | |
| 
 | |
| \fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
 | |
| 
 | |
| \fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -
 | |
| 
 | |
| \fILIBSSH2_ERROR_PUBLICKEY_UNVERIFIED\fP - The username/public key
 | |
| combination was invalid.
 | |
| 
 | |
| \fILIBSSH2_ERROR_AUTHENTICATION_FAILED\fP - Authentication using the supplied
 | |
| public key was not accepted.
