# libssh2\_sftp\_seek64(3)

set the read/write position within a file

## NAME

libssh2\_sftp\_seek64 - set the read/write position within a file

## SYNOPSIS

```
#include <libssh2.h>
#include <libssh2_sftp.h>
void
libssh2_sftp_seek64(LIBSSH2_SFTP_HANDLE *handle,
                    libssh2_uint64_t offset);
```

## DESCRIPTION

*handle* - SFTP File Handle as returned by **[libssh2\_sftp\_open\_ex(3)](/libssh2_sftp_open_ex/3.md)**

*offset* - Number of bytes from the beginning of file to seek to.

Move the file handle's internal pointer to an arbitrary location. libssh2 implements file pointers as a localized concept to make file access appear more POSIX like. No packets are exchanged with the server during a seek operation. The localized file pointer is used as a convenience offset during read/write operations.

You MUST NOT seek during writing or reading a file with SFTP, as the internals use outstanding packets and changing the "file position" during transit will results in badness.
