Add a new function `libssh2_sftp_posix_rename_ex()` and `libssh2_sftp_posix_rename()`, which implement the posix-rename@openssh.com extension. If the server does not support this extension, the function returns `LIBSSH2_FX_OP_UNSUPPORTED` and it's up to the user to recover, possibly by calling `libssh2_sftp_rename()`. Co-authored-by: Viktor Szakats (bump to size_t) Closes #1386

libssh2_sftp_posix_rename_ex - rename an SFTP file using POSIX semantics

.SH DESCRIPTION
|
|
\fIsftp\fP - SFTP instance as returned by
|
|
.BR libssh2_sftp_init(3)
|
|
|
|
\fIsourcefile\fP - Path and name of the existing filesystem entry
|
|
|
|
\fIsourcefile_len\fP - Length of the path and name of the existing
|
|
filesystem entry
|
|
|
|
\fIdestfile\fP - Path and name of the target filesystem entry
|
|
|
|
\fIdestfile_len\fP - Length of the path and name of the target
|
|
filesystem entry
|
|
|
|
This function implements the posix-rename@openssh.com extension, which is
|
|
useful when, for example, moving files across filesystems on a remote server.
|
|
SSH_FXP_RENAME does not specify a specific implementation, but many servers
|
|
will attempt to user hard links when moving files using SSH_FXP_RENAME.
|
|
|
|
If the server does not support posix-rename@openssh.com, this function will
|
|
return LIBSSH2_FX_OP_UNSUPPORTED and you can call libssh2_sftp_rename_ex (3) as
|
|
a backup.
|
|
.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_FX_OP_UNSUPPORTED\fP - Server does not support
|
|
posix-rename@openssh.com
|
|
|
|
\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_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
|
|
received on the socket, or an SFTP operation caused an errorcode to
|
|
be returned by the server.
