# libssh2\_scp\_send64(3)

Send a file via SCP

## NAME

libssh2\_scp\_send64 - Send a file via SCP

## SYNOPSIS

```
#include <libssh2.h>
LIBSSH2_CHANNEL *
libssh2_scp_send64(LIBSSH2_SESSION *session, const char *path, int mode,
                   libssh2_uint64_t size, time_t mtime, time_t atime);
```

## DESCRIPTION

*session* - Session instance as returned by **[libssh2\_session\_init\_ex(3)](/libssh2_session_init_ex/3.md)**

*path* - Full path and filename of file to transfer to. That is the remote file name.

*mode* - File access mode to create file with

*size* - Size of file being transmitted (Must be known ahead of time). Note that this needs to be passed on as variable type libssh2\_uint64\_t. This type is 64 bit on modern operating systems and compilers.

*mtime* - mtime to assign to file being created

*atime* - atime to assign to file being created (Set this and mtime to zero to instruct remote host to use current time).

Send a file to the remote host via SCP.

## RETURN VALUE

Pointer to a newly allocated LIBSSH2\_CHANNEL instance, or NULL on errors.

## ERRORS

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

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

*LIBSSH2\_ERROR\_SCP\_PROTOCOL* -

*LIBSSH2\_ERROR\_EAGAIN* - Marked for non-blocking I/O but the call would block.
