Deprecated
  Please use SFTP instead

  ssh_scp_init()

## ◆ ssh_scp_deny_request()

int ssh_scp_deny_request | ( | ssh_scp | scp,

Deprecated
  Please use SFTP instead

Parameters

  [in] | scp | The scp handle.
  [in] | reason | A nul-terminated string with a human-readable explanation of the deny.

Returns
  SSH_OK if the message was sent, SSH_ERROR if the sending the message failed, or sending it in a bad state.

## ◆ ssh_scp_free()

void ssh_scp_free | ( | ssh_scp | scp | ) |

Free a scp context.

Deprecated
  Please use SFTP instead

Parameters

  [in] | scp | The context to free.

  ssh_scp_new()

## ◆ ssh_scp_init()

int ssh_scp_init | ( | ssh_scp | scp | ) |

Initialize the scp channel.

Deprecated
  Please use SFTP instead

Parameters

  [in] | scp | The scp context to initialize.

Returns
  SSH_OK on success or an SSH error code.

See also
  ssh_scp_new()

## ◆ ssh_scp_integer_mode()

int ssh_scp_integer_mode | ( | const char * | mode | ) |

Convert a scp text mode to an integer.

Deprecated
  Please use SFTP instead

Parameters

  [in] | mode | The mode to convert, e.g. "0644".

Returns
  An integer value, e.g. 420 for "0644".

## ◆ ssh_scp_leave_directory()

int ssh_scp_leave_directory | ( | ssh_scp | scp | ) |

Leave a directory.

Deprecated
  Please use SFTP instead

Returns
  SSH_OK if the directory has been left, SSH_ERROR if an error occurred.

## ◆ ssh_scp_new()

ssh_scp ssh_scp_new | ( | ssh_session | session,
|  | int | mode,
|  | const char * | location )

Create a new scp session.

Deprecated
  Please use SFTP instead

Parameters

  [in] | session | The SSH session to use.
  [in] | mode | One of SSH_SCP_WRITE or SSH_SCP_READ, depending if you need to drop files remotely or read them. It is not possible to combine read and write. SSH_SCP_RECURSIVE Flag can be or'ed to this to indicate that you're going to use recursion. Browsing through directories is not possible without this.
  [in] | location | The directory in which write or read will be done. Any push or pull will be relative to this place. This can also be a pattern of files to download (read).

Returns
  A ssh_scp handle, NULL if the creation was impossible.

## ◆ ssh_scp_pull_request()

int ssh_scp_pull_request | ( | ssh_scp | scp | ) |

Wait for a scp request (file, directory).

Deprecated
  Please use SFTP instead

Returns
  SSH_SCP_REQUEST_NEWFILE: The other side is sending a file SSH_SCP_REQUEST_NEWDIR: The other side is sending a directory SSH_SCP_REQUEST_ENDDIR: The other side has finished with the current directory SSH_SCP_REQUEST_WARNING: The other side sent us a warning SSH_SCP_REQUEST_EOF: The other side finished sending us files and data. SSH_ERROR: Some error happened
