.IP LIBSSH2_FXF_READ
|
|
Open the file for reading.
|
|
.IP LIBSSH2_FXF_WRITE

.IP LIBSSH2_FXF_APPEND
|
|
Force all writes to append data at the end of the file.

already exist (if LIBSSH2_FXF_TRUNC is specified, the new file will be
|
|
truncated to zero length if it previously exists)
|
|
.IP LIBSSH2_FXF_TRUNC

|
Forces an existing file with the same name to be truncated to zero length when
|

be specified if this flag is used.
|
|
.IP 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.
|
|
|
|

|
|
created. See the LIBSSH2_SFTP_S_* convenience defines in <libssh2_sftp.h>
