 long mode, int open_type);

Description

sftp – SFTP instance as returned by libssh2_sftp_init(3)

filename – Remote file/directory resource to open

filename_len – Length of filename

flags – Any reasonable combination of the LIBSSH2_FXF_* constants:

LIBSSH2_FXF_READ

Open the file for reading.

LIBSSH2_FXF_WRITE

Open the file for writing. If both this and LIBSSH2_FXF_READ are specified, the file is opened for both reading and writing.

LIBSSH2_FXF_APPEND

Force all writes to append data at the end of the file.

LIBSSH2_FXF_CREAT,

If this flag is specified, then a new file will be created if one does not already exist (if LIBSSH2_FXF_TRUNC is specified, the new file will be truncated to zero length if it previously exists)

LIBSSH2_FXF_TRUNC

Forces an existing file with the same name to be truncated to zero length when creating a file by specifying LIBSSH2_FXF_CREAT. LIBSSH2_FXF_CREAT MUST also be specified if this flag is used.

LIBSSH2_FXF_EXCL

Causes the request to fail if the named file already exists. LIBSSH2_FXF_CREAT MUST also be specified if this flag is used.

mode – POSIX file permissions to assign if the file is being newly created. See the LIBSSH2_SFTP_S_* convenience defines in <libssh2_sftp.h>

open_type – Either of LIBSSH2_SFTP_OPENFILE (to open a file) or LIBSSH2_SFTP_OPENDIR (to open a directory).

Return Value

A pointer to the newly created LIBSSH2_SFTP_HANDLE instance or NULL on failure.

Errors

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.

LIBSSH2_ERROR_EAGAIN – Marked for non-blocking I/O but the call would block.
