libssh2_sftp_open_ex_r(3) libssh2 libssh2_sftp_open_ex_r(3)
NAME libssh2_sftp_open_ex_r - open filehandle for file on SFTP.
SYNOPSIS #include <libssh2.h> #include <libssh2_sftp.h>
LIBSSH2_SFTP_HANDLE * libssh2_sftp_open_ex_r(LIBSSH2_SFTP *sftp, const char *filename, size_t filename_len, unsigned long flags, long mode, int open_type, LIBSSH2_SFTP_ATTRIBUTES *attrs);
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 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.
