# libssh2\_sftp\_posix\_rename\_ex(3)

rename an SFTP file using POSIX semantics

## NAME

libssh2\_sftp\_posix\_rename\_ex - rename an SFTP file using POSIX semantics

## SYNOPSIS

```
#include <libssh2.h>
#include <libssh2_sftp.h>
int
libssh2_sftp_posix_rename_ex(LIBSSH2_SFTP *sftp,
                             const char *source_filename,
                             size_t source_filename_len,
                             const char *dest_filename,
                             size_t dest_filename_len);
```

## DESCRIPTION

*sftp* - SFTP instance as returned by **[libssh2\_sftp\_init(3)](/libssh2_sftp_init/3.md)**

*sourcefile* - Path and name of the existing filesystem entry

*sourcefile\_len* - Length of the path and name of the existing filesystem entry

*destfile* - Path and name of the target filesystem entry

*destfile\_len* - 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.

## 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.

## ERRORS

*LIBSSH2\_FX\_OP\_UNSUPPORTED* - Server does not support posix-rename@openssh.com

*LIBSSH2\_ERROR\_ALLOC* - An internal memory allocation call failed.

*LIBSSH2\_ERROR\_SOCKET\_SEND* - Unable to send data on socket.

*LIBSSH2\_ERROR\_SOCKET\_TIMEOUT* -

*LIBSSH2\_ERROR\_SFTP\_PROTOCOL* - An invalid SFTP protocol response was received on the socket, or an SFTP operation caused an errorcode to be returned by the server.
